Lord Gauranga
Gauranga (the golden one) refers to Lord Caitanya, who has a fair complexion. The Lord's acceptance of the role of a devotee in the eternal form of Lord Sri Caitanya Mahaprabhu is another of the Lord's wonderful features. A conditioned soul cannot reach the absolute Personality of Godhead by his imperfect endeavor, therefore Lord Sri Krsna, in the form of Lord Gauranga, has made it easy for everyone to approach Him. As Lord Gauranga is the form of a devotee, Nityananda Prabhu (a manifestation of Balarama) appears in the form of a devotee's spiritual master. Together, they are referred to as Guru and Gauranga, or Nitai-Gauranga.
