As the gopīs and Kṛṣṇa danced together, a very blissful musical sound was produced from the tinkling of their bells, ornaments and bangles. It appeared that Kṛṣṇa was a greenish sapphire locket in the midst of a golden necklace decorated with valuable stones. While Kṛṣṇa and the gopīs danced, they displayed extraordinary bodily features. The movements of their legs, their placing their hands on one another, the movements of their eyebrows, their smiling, the movements of the gopīs' breasts, clothes and earrings, their cheeks, their hair with flowers—as Kṛṣṇa and the gopīs sang and danced these combined to appear like clouds, thunder, snow and lightning. Kṛṣṇa's bodily features appeared just like a group of clouds, the gopīs' songs were like thunder, their beauty appeared to be just like lightning in the sky, and the drops of perspiration visible on their faces appeared like falling snow. In this way, the gopīs and Kṛṣṇa fully engaged in dancing.
The necks of the gopīs became tinted with red due to their desire to enjoy Kṛṣṇa more and more. To satisfy them, Kṛṣṇa began to clap His hands in time with their singing. Actually the whole world is full of Kṛṣṇa's singing, but it is appreciated in different ways by different kinds of living entities. This is confirmed in the Bhagavad-gītā: ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy aham (BG 4.11). Kṛṣṇa is dancing, and every living entity is also dancing, but there is a difference between the dancing in the spiritual world and that in the material world. This is expressed by the author of the Caitanya-caritāmṛta, who says that the master dancer is Kṛṣṇa and everyone else is His servant. Everyone is trying to imitate Kṛṣṇa's dancing. Those who are actually in Kṛṣṇa consciousness respond rightly to the dancing of Kṛṣṇa: they do not try to dance independently. But those in the material world try to imitate Kṛṣṇa as the Supreme Personality of Godhead. The living entities are dancing under the direction of Kṛṣṇa's māyā and are thinking that they are equal to Kṛṣṇa. But this is not a fact. In Kṛṣṇa consciousness, this misconception is absent, for a person in Kṛṣṇa consciousness knows that Kṛṣṇa is the supreme master and everyone else is His servant. One has to dance to please Kṛṣṇa, not to imitate or attempt to become equal to the Supreme Personality of Godhead. The gopīs wanted to please Kṛṣṇa, and therefore as Kṛṣṇa sang, they responded and encouraged Him by saying "Well done! Well done!" Sometimes they presented beautiful music for His pleasure, and He responded by praising their singing.
