The word “Krishna” means “the all-attractive” current in ISKCON is due to Prabhupada’s commentary on Bhagavata Purana (1.1.1) and (6.4.33) because according to Gaudiya philosophy the Lord is sometimes called gu?a-karma-n?ma because He is named according to His transcendental activities.

Thus, Krishna in this context means “all-attractive”, because “His transcendental qualities make Him very attractive.”Prabhupada bases this on his translation of the Chaitanya Charitamrita, where a mystical “etymology” of k???a is given as

k??ir bh?-v?caka? ?abdo / ?a? ca nirv?ti-v?caka?
“k?? expresses existence (bh?); ?a expresses pleasure (nirv?ti)”

The translation of bh? given by Prabhupada is “attractive existence”.

Shri Krishna Vasudeva
The cult of Krishna V?sudeva (IAST k???a v?sudeva “Krishna, son of Vasudeva”) is historically one of the earliest forms of worship in Krishnaism and Vaishnavism. It is believed to be a significant tradition of the early history of the worship of Krishna in antiquity. This tradition is considered separately to other traditions that led to amalgamation at a later stage of the historical development. Other traditions are Bhagavatism and Cult of Gopala, that along with Cult of Bala-Krishna form the basis of current tradition of monotheistic religion of Krishna. Some early scholars would equate it with Bhagavatism, and the founder of this religious tradition is believed to be Krishna, who is the son of Vasudeva, thus his name is V?sudeva, he is belonged to be historically part of the Satvata tribe, and according to them his followers called themselves Bhagavatas and this religion had formed by the 2nd century BC (the time of Patanjali), or as early as the 4th century BC according to evidence in Megasthenes and in the Arthasastra of Kautilya, when V?sudeva was worshiped as supreme Deity in a strongly monotheistic format, where the supreme Being was perfect, eternal and full of grace. In many sources outside of the cult, devotee or bhakta is defined as V?sudevaka.

The Harivamsa describes intricate relationships between Krishna Vasudeva, Sankarsana, Pradyumna and Aniruddha that would later form a Vaishnava concept of primary quadrupled expansion, or avatara.
