Lord Sri Krsna expanded Himself into many forms while engaged in the rasa-lila dance, and He also expanded Himself when He married 16,000 wives in Dvaraka. The same process was adopted by Sri Caitanya Mahaprabhu when He expanded Himself into seven forms to dance in each and every group of the sankirtana party. These expansions were appreciated by pure devotees, including King Prataparudra. Although for reasons of external formality Sri Caitanya Mahaprabhu refused to see King Prataparudra because he was a king, King Prataparudra became one of the Lord's most confidential devotees by the Lord's special mercy upon Him. The King could see Sri Caitanya Mahaprabhu simultaneously present in all seven groups. As confirmed in Srimad-Bhagavatam, one cannot see the expansions of the transcendental forms of the Lord unless one is a pure devotee of the Lord.
