Janmashtami
What it is
Janmashtami celebrates the birth of Shri Krishna on the eighth day of the dark half of Shravan — Shravan Vad Aatham — at midnight, under the Rohini nakshatra. The katha is the most beloved in all of bhakti: Mathura groaning under Kansa; Devakiji and Vasudevji imprisoned; seven children lost; and then, at the blackest hour of a storming night, the eighth — Prabhu himself — appearing in the prison, the chains falling open, the doors unbarring, and Vasudevji carrying the newborn across the swollen Yamunaji to Gokul, to the house of Nandbaba and Yashodaji, where he would be raised in love.
In Pushtimarg havelis the day is kept with fasting and jagran. Shri Thakorji receives panchamrut snan — milk, curd, ghee, honey and sugar — and abhyang; the shringar and bhog carry the bhav of welcome. As midnight arrives the birth is celebrated with aarti, the shankh sounds, and at Nathdwara cannon salutes thunder over the town; then the newborn Lala is placed in the palna and rocked, while kirtans of the janma fill the haveli.
Why we observe it
For a Pushtimarg Vaishnav this is not the remembrance of a long-ago event but a prakatya — a manifestation — that happens for the bhakta's sake, tonight, in the bhakta's own heart. Shri Mahaprabhuji taught that Shri Krishna is Purna Purushottam, the complete Godhead, and that he appears not to fulfil prophecy but out of love, to give his devotees the joy of him. So the Vaishnav does not merely commemorate; the Vaishnav waits — fasting through the day, singing through the night — the way Vraj waited without knowing what it waited for.
And the birth itself carries the marg's whole teaching: Prabhu chooses to arrive as an infant, utterly dependent, so that love may serve him. He could have come as the conqueror; he came as a child needing Yashodaji's arms. That is pushti — grace that gives itself into our hands. When the palna rocks at midnight and 'Nand ke ghar anand bhayo' rings out, every Vaishnav's home becomes Gokul, every heart a cradle, and the year's deepest truth is renewed: the Lord of all is born small, so that we may love him.
