Big Data

Big data can be explained by understanding the following key aspects:

Big Data
Big Data
  1. Volume. There is no specific quantification that says volume above these many terabytes will be called Big data. What volume one considers as threshold depends on the perspective and the year we are in (big data is a moving target). However, this large volume of data is mostly the cost-free byproduct of digital interaction such as consumers buying stuff off online shops.
  2. Velocity. The speed at which data is generated and processed. Big data is often available in real time.
  3. Variety. The type and nature of data. Big data draws from text, images, audio, video; plus it completes missing pieces through data fusion.
  4. Data must be processed with advanced tools (analytics and algorithms) to reveal meaningful information. Big data is not about asking why, but about detecting patterns. Information generation algorithms must detect and address visible and invisible issues and factors.
  5. Parallel computing tools are needed to handle data.
  6. Often “inductive statistics” are used to infer laws (relationships, causal effects) from large sets of data to reveal relationships or dependencies or to perform predictions of outcomes and behaviours.

Supermoon and Gurpurab

Guru Nanak Dev ji was the founder of Sikhism. Sikhs believe Him to be God in a Human form. His teachings are embodied in Scripture form: Guru Granth Sahib ji.

Traditionally, Guru Nanak Dev ji’s prakash purab (the day He spread forth His light on this earth) is celebrated on the full moon night of a specific lunar month. This year, this day coincided with the Supermoon. Here is a photo of the Golden Temple with the supermoon visible in the background:

My message sent out for this year’s Gurpurab greeting:

Kot karam karai hao dhare || Sram pavai sagle birthare || (278)

Hao vich maya, Hao vich chhaya || (466)

Kirpa kare je aapni, tan Gur ka Shabad kamahe || Nanak kahai sunho jano, eet sanjam dukh jai || (466)

Kaho Nanak nihchou dhyave || Vin Satgur vaat na pavai || (470)

By engaging in good deeds alone we cannot lose our egoistical pride. This pride causes to remain attached to Maya, and deprives us from appreciating Divine Bounties. Even millions of good deeds, done under the false influence of Maya – go waste. While we may have laboured, we do not receive Divine Respect. Reciting the Lord’s Name under the True Guru’s instructions, this veil of ego is removed and we are enraptured in Divine Love. Such a path is obtained by great fortune, and through the Lotus Feet of the Guru. Dhan Guru Nanak.

One of the central teachings of Guru Nanak was to see God as embodied in His Creation and recitation of His Greatness with loving devotion.

Updating Sony Xperia Z2 to Android Marshmallow

Having waited for several days for the update to be pushed to my phone, I temporarily moved over from Airtel to Vodafone. Wow! the update was pushed within seconds – after I connected to the PC using the Xperia Companion software. Airtel seems to be helplessly slow in pushing this update (or perhaps it decided not to go ahead with this one).

Bye Bye Lollipop… 🙂

Basant Panchami

Today is Basant Panchami, an Indian festival of spring. The flowers are in full bloom – an image below, shot and edited completely on my Sony Xperia Z2. There are lots of colours all around.

Sikhism believes only in worship of One God, Who is Unborn and all pervading. He is the Creator, the Preserver and the Destroyer. The following is a translation of Basant Ki Vaar (Ode of Basant) by the Fifth Guru, Guru Arjan Dev ji. While spring is one of the four seasons, here Guru ji speaks of everlasting spring within our heart and mind which is the culmination of worship and surrender to God.

Guru Nanak gurpurab greetings

November 17th is being celebrated this year as the day Guru Nanak came to this earth. The foremost of His teachings was to stay detached from Maya (worldly pleasures) and always thank the Creator for his bounties. Simple living and serving to other beings were advocated.

Sharing below a greeting card which can be used to spread His Divine Message. (Click on the image to see bigger, two versions)

Message of Guru Nanak

Gurpurab Guru Nanak Dev ji

This first quote about Guru Nanak’s coming to this earth is from a ballad by Bhai Gurdas (Vaar 1, Pauri 24). The second quote, Guru Nanak’s message about devotion and humility is from Guru Nanak’s primary writing “Asa ki vaar“, and appears within Sri Guru Granth Sahib at Ang 470. Recital of God’s name under Guru’s guidance is important towards separating oneself from Maya (worldly pleasures) which then leads you to God.

Places of pilgrimage in Sikhism

Takht
Takht

Recently returned from a visit to Sachkhand Sri Hazur Sahib. This was the last residing place for the Tenth Guru. The journey was enjoyable, and the time spent very gainfully. I wished I could stay a few more days.

On the way, I spent some time thinking about what would constitute the most important place of pilgrimage. I share below some thoughts by the Gurus on this:

  1. The feet of the Holy
  2. Our mind and home
  3. The Lord’s name and discussion of the Divine Word
  4. The congregation of the Holy
  5. Satguru, the Divine Guide

The feet of the Holy:

ਜਨ ਪਾਰਬ੍ਰਹਮ ਜਾ ਕੀ ਨਿਰਮਲ ਮਹਿਮਾ ਜਨ ਕੇ ਚਰਨ ਤੀਰਥ ਕੋਟਿ ਗੰਗਾ ॥
Jan pārbarahm jā kī nirmal mahimā jan ke cẖaran ṯirath kot gangā.
Immaculate and pure are the praises of the humble servants of the Supreme Lord God; the feet of His humble servants are equal to millions of Ganges (sacred shrines of pilgrimage).

 

Our mind and home:

ਮਨੁ ਮੰਦਰੁ ਤਨੁ ਵੇਸ ਕਲੰਦਰੁ ਘਟ ਹੀ ਤੀਰਥਿ ਨਾਵਾ ॥
Man manḏar ṯan ves kalanḏar gẖat hī ṯirath nāvā.
The Lord’s Name enshrined within, my mind has become a temple. My body is the simple cloth of the humble seeker; and my home is the bathing of a sacred pilgrimage.

 

The Lord’s name and discussion of the Divine Word:

ਤੀਰਥਿ ਨਾਵਣ ਜਾਉ ਤੀਰਥੁ ਨਾਮੁ ਹੈ ॥
Ŧirath nāvaṇ jā▫o ṯirath nām hai.
Lets all bathe at sacred shrines: The Naam, the Name of the Lord, is the sacred shrine of pilgrimage.
ਤੀਰਥੁ ਸਬਦ ਬੀਚਾਰੁ ਅੰਤਰਿ ਗਿਆਨੁ ਹੈ ॥
Ŧirath sabaḏ bīcẖār anṯar gi▫ān hai.
My sacred shrine of pilgrimage is contemplation of Divine Words, which leads to spiritual wisdom within.

 

The congregation of the Holy:

ਰਾਮਦਾਸਿ ਸਰੋਵਰ ਨਾਤੇ ॥
Rāmḏās sarovar nāṯe.
By bathing in a pool of God Servants
ਸਭ ਲਾਥੇ ਪਾਪ ਕਮਾਤੇ ॥੨॥
Sabẖ lāthe pāp kamāṯe. ||2||
all the sins committed are washed off.

 

Satguru, the Divine Guide:

ਤੀਰਥੁ ਪੂਰਾ ਸਤਿਗੁਰੂ ਜੋ ਅਨਦਿਨੁ ਹਰਿ ਹਰਿ ਨਾਮੁ ਧਿਆਏ ॥
Ŧirath pūrā saṯgurū jo an▫ḏin har har nām ḏẖi▫ā▫e.
The True Guru is the Perfect Pilgrimage, Who remains ever absorbed in the Lord’s Name – night and day.

 

So, what does this mean? Should we not visit physical places of pilgrimage like Hazur Sahib?
We should because our mind has not yet been purified, and needs to understand the Guru’s Word. However, when we are at a place of pilgrimage, we should engage in these True Pilgrimage activities and not just enjoy visiting and babbling. Sikhism is perhaps unique in this respect.

Holi

Holi
Holi

I have written about many Indian festivals, but never about Holi. It is the Hindu festival of colours, much like Diwali being the festival of lights.

For Sikhism, colours are strong depictions of mental state. There is no physical relevance to colours. A Sikh is expected to wear ordinary clothes that do not attract attention. Neither is playing with colours encouraged.

A key ingredient used during holi is called Gulal. Its a deep red coloured powder which is used to colour others. The Guru says this about Gulal:

ਚੀਤਿ ਆਵੈ ਤਾਂ ਰੰਗਿ ਗੁਲਾਲ ॥
When my mind is attached to Him, I am dyed in the deep crimson of His Love.

In the daily Sikh prayer, the first reference to the word colour appears in Japuji Sahib.

ਭਰੀਐ ਮਤਿ ਪਾਪਾ ਕੈ ਸੰਗਿ ॥
But when the intellect is stained and polluted by sins committed by us,

ਓਹੁ ਧੋਪੈ ਨਾਵੈ ਕੈ ਰੰਗਿ ॥
it can only be cleansed by the colour (Love) of His Name.

Sri Guru Granth Sahib recognises two colours: Kusumbh and Majith. Kusumbh is light orange in colour, while Majith is dark red, even crimson. Kusumbh is the color of a flower (Butea monosperma) called “flame of the forest” (called FF henceforth in this post). When its immersed in water for a few hours, the flower looses its colour, and the water becomes coloured.

When Guru Nanak was visiting Mecca, he was asked whether Hinduism was the greater religion or Islam. His reply was as under:

ਕਚਾ ਰੰਗੁ ਕਸੁੰਭ ਦਾ ਪਾਣੀ ਧੋਤੈ ਥਿਰ ਨ ਰਹੋਈ।
As the colour of FF flower is impermanent and is washed away in water, likewise the colours of religiosity are also temporary.

To the contrary, majith is permanent. Its effects are not physical, rather its colouring is for the soul:

ਮਨਮੁਖੁ ਰੰਗੁ ਕਸੁੰਭੁ ਹੈ ਕਚੂਆ ਜਿਉ ਕੁਸਮ ਚਾਰਿ ਦਿਨ ਚਾਗਾ ॥
The self-willed manmukh is like the false color of the FF flower, which fades away; its color lasts for only a few days.

ਖਿਨ ਮਹਿ ਬਿਨਸਿ ਜਾਇ ਪਰਤਾਪੈ ਡੰਡੁ ਧਰਮ ਰਾਇ ਕਾ ਲਾਗਾ ॥੨॥
He perishes in an instant; he is tormented, and punished by the Righteous Judge of Dharma. ||2||

ਸਤਸੰਗਤਿ ਪ੍ਰੀਤਿ ਸਾਧ ਅਤਿ ਗੂੜੀ ਜਿਉ ਰੰਗੁ ਮਜੀਠ ਬਹੁ ਲਾਗਾ ॥
The Lord’s Love, found in the Sat Sangat, the True Congregation, is absolutely permanent, and colorfast.

ਕਾਇਆ ਕਾਪਰੁ ਚੀਰ ਬਹੁ ਫਾਰੇ ਹਰਿ ਰੰਗੁ ਨ ਲਹੈ ਸਭਾਗਾ ॥੩॥
The cloth of the body may be torn to shreds, but still, this beautiful color of the Lord’s Love does not fade away. ||3||

ਹਰਿ ਚਾਰ੍ਹਿਓ ਰੰਗੁ ਮਿਲੈ ਗੁਰੁ ਸੋਭਾ ਹਰਿ ਰੰਗਿ ਚਲੂਲੈ ਰਾਂਗਾ ॥
Meeting with the Blessed Guru, one is dyed in the color of the Lord’s Love, imbued with this deep crimson color.

So how does the Guru celebrate Holi. The answer is obvious:

ਹੋਲੀ ਕੀਨੀ ਸੰਤ ਸੇਵ ॥
Holī kīnī sanṯ sev.
I celebrate the festival of Holi by serving the Saints.

ਰੰਗੁ ਲਾਗਾ ਅਤਿ ਲਾਲ ਦੇਵ ॥੨॥
Rang lāgā aṯ lāl ḏev. ||2||
I am imbued with the deep crimson color of the Lord’s Divine Love. ||2|

Finally I want to share another related hymn:

ਲਾਲ ਰੰਗੁ ਤਿਸ ਕਉ ਲਗਾ ਜਿਸ ਕੇ ਵਡਭਾਗਾ ॥
One is dyed in the (red) color of the Lord’s Love, by great good fortune.

ਮੈਲਾ ਕਦੇ ਨ ਹੋਵਈ ਨਹ ਲਾਗੈ ਦਾਗਾ ॥੧॥
This color is never muddied; no stain ever sticks to it. ||1||

ਪ੍ਰਭੁ ਪਾਇਆ ਸੁਖਦਾਈਆ ਮਿਲਿਆ ਸੁਖ ਭਾਇ ॥
He finds God, the Giver of peace, with feelings of joy.

ਸਹਜਿ ਸਮਾਨਾ ਭੀਤਰੇ ਛੋਡਿਆ ਨਹ ਜਾਇ ॥੧॥ ਰਹਾਉ ॥
The Celestial Lord blends into his soul, and he can never leave Him. ||1||Pause||

ਜਰਾ ਮਰਾ ਨਹ ਵਿਆਪਈ ਫਿਰਿ ਦੂਖੁ ਨ ਪਾਇਆ ॥
Old age and death cannot touch him, and he shall not suffer pain again.

ਪੀ ਅੰਮ੍ਰਿਤੁ ਆਘਾਨਿਆ ਗੁਰਿ ਅਮਰੁ ਕਰਾਇਆ ॥੨॥
Drinking in the Ambrosial Nectar, he is satisfied; the Guru makes him immortal. ||2||
