The Supreme Personality of Godhead, appearing in His original, two-armed, form,
who is the origin of all of the Lord's other forms and incarnations (avataras). He was born as the ninth avatara of Vishnu, and the twentieth purusha incarnation. He was the son of Vasudeva and Devaki. This romantic cowherd figure is regarded by the Hare Krishna movement
to be the Supreme Personality of Godhead, and all other figures (including
the Hindu Trinity of Brahma, Vishnu and Shiva) are demoted/relegated
to the position of demigods. He is described in the Srimad Bhagavatam, thus:
vrishnishu prapya janmani
rama-krishnav iti bhuvo
bhagavan aharad bharam
In the nineteenth and twentieth incarnations, the Lord advented himself as Lord
Balarama and Lord Krishna in the family of Vrishni [the
Yadu dynasty], and by so doing He removed the burden of the world."
Bhag., Canto 1, Ch. 3, Text 23
klesha-vyayaya kalaya sita-krishna-keshah
jatah karishyati jananupalakshya-margah
When the world is overburdened by the fighting strength of kings who have no faith
in God, the Lord, just to diminish the distress fo the world, descends with His plenary
portion. The Lord come in His original form, with beautiful black hair. And just to expand
His transcendental glories, He acts extraordinarily. No one can properly estimate
how great He is..."
Bhag., Canto 2, Ch. 7, Text 26, et. seq.
