Śrī Śukadeva Gosvāmī continued: One day when mother Yaśodā saw that all the maidservants were engaged in other household affairs, she personally began to churn the yogurt. While churning, she remembered the childish activities of Kṛṣṇa, and in her own way she composed songs and enjoyed singing to herself about all those activities.
Śrīla Viśvanātha Cakravartī Ṭhākura, quoting from the Vaiṣṇava-toṣaṇī of Śrīla Sanātana Gosvāmī, says that the incident of Kṛṣṇa's breaking the pot of yogurt and being bound by mother Yaśodā took place on the Dīpāvalī Day, or Dīpa-mālikā. Even today in India, this festival is generally celebrated very gorgeously in the month of Kārtika by fireworks and lights, especially in Bombay. It is to be understood that among all the cows of Nanda Mahārāja, several of mother Yaśodā's cows ate only grasses so flavorful that the grasses would automatically flavor the milk. Mother Yaśodā wanted to collect the milk from these cows, make it into yogurt and churn it into butter personally, since she thought that this child Kṛṣṇa was going to the houses of neighborhood gopas and gopīs to steal butter because He did not like the milk and yogurt ordinarily prepared.

Śrī Caitanya Mahāprabhu and His devotees participated in all the festivals, including Rāsa-yātrā, Dīpāvalī and Utthāna-dvādaśī.
The Dīpāvalī festival takes place on the dark-moon night in the month of Kārtika (October-November). The Rāsa-yātrā, or rāsa dancing of Kṛṣṇa, takes place on the full-moon night of the same month. Utthāna-dvādaśī takes place the day after Ekādaśī in the waxing fortnight of the moon in the same month. All the devotees of Śrī Caitanya Mahāprabhu participated in all these festivals.
(Sri Caitanya Caritamrta------2:15:36------translation and purport).

The roads, streets and lanes of Hastināpura were all sprinkled with fragrant water through the trunks of intoxicated elephants. In different places of the city there were colorful festoons and flags decorating the houses and streets. At important crossroads there were gates with golden decorations, and at the two sides of the gates there were golden water jugs. These beautiful decorations glorified the opulence of the city. Participating in this great ceremony, all the citizens gathered here and there, dressed in colorful new clothing and decorated with ornaments, flower garlands and fragrant scents. The houses were all illuminated by hundreds and thousands of lamps placed in different corners of the cornices, walls, columns, bases and architraves, and from far away the rays of the lamps appeared to be celebrating the festival of Dīpāvalī (a particular festival observed on the New Year's Day of the Hindu calendar). Within the walls of the houses, fragrant incense was burning, and smoke rose through the windows, making the entire atmosphere very pleasing. On the top of every house, flags were flapping, and the golden waterpots kept on the roofs shone brilliantly.
