Shri Venkateshwara

Lord Balaji is a Krishna Deity. The deity of Balaji is two handed Krishna deity. The very name “balaji” means child Lord. There is no such thing as a Bala Vishnu, only a Bala Gopal, or child form of Krishna. The name Balaji refers to Lord Krishna as a child. This is further confirmed by the fact that all visiting devotees call out his name as “Govinda, Govinda, Goooovinda” while they walk up the mountain. As everyone knows, the name Govinda refers to Gopala Krishna, the cowherd boy, not to four-armed Narayana.

In a 1974 edition of Back To Godhead, an article appeared titled "Secretary to a Pure Devotee". In that article, Srila Prabhupada's opinion on this Deity was stated as follows: "In the cottage there was a picture of the Balaji Deity. Prabhupada said that the Deity's name means "child," Krishna as a cowherd boy, not in His Vaikuntha aspect [His majestic form in the spiritual planets]."
Srila Prabhupada has also stated the following while visiting Andhra Pradesh:
"Still, in India there are many devotees, many Krishna conscious persons. Especially in this province. You are very great devotees of Balaji. Balaji is Krishna, Bala Krishna So I wish that the government may be conducted under the guide of Balaji, Lord Krishna. That is my request."
The Balaji Deities installed in ISKCON temples are not four-handed Vishnu Deities, but two-handed Deities of Bala Krishna.
