The Mahābhārata, is the greatest, longest and one of the two major Sanskrit epics of ancient India, the other being the Rāmāyana. With more than 74,000 verses, plus long prose passages, or some 1.8 million words in total, it is one of the longest epic poems in the world.

It contains eighteen Parvas or sections viz., Adi Parva, Sabha Parva, Vana Parva, Virata Parva, Udyoga Parva, Bhishma Parva, Drona Parva, Karna Parva, Shalya Parva, Sauptika Parva, Stree Parva, Shanti Parva, Anushasana Parva, Asvamedha Parva, Ashramavasika Parva, Mausala Parva, Mahaprasthanika Parva and Swargarohanika Parva. Each Parvacontains many sub-Parvas or subsections.

This wonderful book was composed by Sri Vyasa (Krishna Dvaipayana) who was the grandfather of the heroes of the epic. He taught this epic to his son Suka and his disciples Vaisampayana and others. King Janamejaya, son of Parikshit, the grandson of the heroes of the epic, performed a great sacrifice. The epic was recited by Vaisampayana to Janamejaya at the command of Vyasa. Later on, Suta recited the Mahabharata as was done by Vaisampayana to Janamejaya, to Saunaka and others, during a sacrifice performed by Saunaka in Naimisaranya, which is near Sitapur in Uttar Pradesh.

Sudama (सुदामा) was a childhood friend of Krishna from Mathura, the story of whose visit to Dwaraka to meet Krishna, is mentioned in the Bhagavata Purana.
Sudama was from a poor Brahmin family, while Krishna was from the royal family. But this difference in social status did not come in the way of their friendship. They lost contact over the years and while Krishna became a military leader and King of great repute at Dwaraka, while Sudama stayed as a humble, and somewhat impoverished Brahmin living in a village [2].
Some time later when Sudama was going through some bad times, not even having enough money to feed his children, his wife reminded him of his friendship with Krishna.
Though initially reluctant to go to his friend for help, Sudama finally agrees to go. He leaves with nothing but some beaten rice tied in a cloth as a present. He remembers that beaten rice (powa/poha in Hindi) is Krishna’s favorite and decided to give this as a gift to the Lord.
Krishna is greatly pleased to see his old friend. He treats him royally and with much love. Overwhelmed by all this Sudama forgets to ask for what he actually came to ask. But the Lord realises what His friend needs, and the lord’s consort Rukmini incarnation of Lakshmi, gifts him with his desires. On his return journey, Sudama ponders his circumstances and is thankful for the great friend he has in Lord Krishna. When Sudama finally returns to his home, he finds a palatial mansion instead of the hut he had left. He also finds his family dressed in extremely nice garb and waiting for him. He lives an austere life after that, always thankful to the Lord.

Krishna is the Supreme Person, the Godhead.

Krishna is the speaker of the Bhagavad-gita, recognized throughout the world as one of mankind’s greatest books of wisdom. In the Gita, as it is also known, Krishna says repeatedly that He is God Himself, the source of everything.

Arjuna, to whom Krishna is speaking, accepts Krishna’s words as true, adding that the greatest spiritual authorities of that time also confirm that Krishna is God. Traditions that follow in the line of these authorities have carried Krishna’s teachings down to the present day.

O Kanha Ab to

O Kaanha, ab toh murli ki, madhur suna do taan,
O Kaanha, ab toh murli ki, madhur suna do taan,
Main hu teri, prem deewani, mujhko tum pehchan,
madhur suna do taan,

O kaanha,ab toh murli ki, madhur suna do taan,
Jabse tum sang maine apne, naina jod liye hai,
Kya maiya kya babul sabse, rishte tod liye hai.
Tere milan ko, vyakul hai ye, kabse mere praan.
madhur suna do taan,

O kaanha, ab toh murli ki, madhur suna do taan,
Saagar se bhi gehari mere, prem ki geheraai, lok, laaj,
Kul ki mariyada, saj kar main toh aayee.
Meri preeti se, o nirmohi, ab na bano anjaan,
madhur suna do taan,
O kaanha, ab toh murli ki, madhur suna do taan,
Main hu teri, prem deewani, mujhko tum pehchan,
madhur suna do taan, madhur suna do taan,
madhur suna do taan.

Lyrics of Krishna song O Kanha ab to in Hindi

ओ कान्हा, अब तोह मुरली की, मधुर सुना दो तान,
ओ कान्हा, अब तोह मुरली की, मधुर सुना दो तान,
में हु तेरी, प्रेम दीवानी, मुझको तुम पहचान,
मधुर सुना दो तान,

ओ कान्हा, अब तोह मुरली की, मधुर सुना दो तान,
जबसे तुम संग मैंने अपने, नैना जोड़ लिए है,
क्या मैया क्या बाबुल सबसे, रिश्ते तोड़ लिए है.
तेरे मिलन को, व्याकुल है ये, कबसे मेरे प्राण.
मधुर सुना दो तान,

ओ कान्हा, अब तोह मुरली की, मधुर सुना दो तान,
सागर से भी गहरी मेरे, प्रेम की गेहेराई, लोक, लाज,
कुल की मरियादा, सज कर में तोह आयी.
मेरी प्रीती से, ओ निर्मोही, अब न बनो अनजान,
मधुर सुना दो तान,

ओ कान्हा, अब तोह मुरली की, मधुर सुना दो तान,
में हु तेरी, प्रेम दीवानी, मुझको तुम पहचान,
मधुर सुना दो तान, मधुर सुना दो तान,
मधुर सुना दो तान.
