The two Lords Gaura and Nitai, also known as Gauranga or Sri Chaitanya Mahaprabhu and Nityananda. Gauranga means ‘One with the golden bodily complexion’ and Nityananda means ‘He who embodies eternal bliss’.
In a special appearance, Krishna personally came in A.D. 1486 as Sri Chaitanya Mahaprabhu and acted as His own devotee. Sri Chaitanya Mahaprabhu is Krishna Himself, saturated with the love for Him that Radha embodies. As the emblem of the perfect devotee of Krishna, He displayed feelings of the highest spiritual ecstasy.
Nityananda Prabhu appeared in the village of Ekachakra, in West Bengal, India, around 1474. In the Caitanya Caritamrita and other scriptures He is declared to be the avatar of Lord Balarama, the direct expansion of the Supreme Personality of Godhead, Krishna.
Krishna taught Bhagavad-gita to liberate all souls, and He returned as Sri Chaitanya to show us how to live by the Gita’s teachings.
Because spiritual realization is difficult in the present age, Krishna as Sri Chaitanya Mahaprabhu is especially liberal. He has made pure love of God attainable by the easy process of chanting His holy names, as in the maha-mantra: Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare.
“In this way, assuming the sentiment of a devotee, He preached devotional service while practicing it Himself.” —Chaitanya-Charitamrita, Adi 4.41
Lord Nityananda, the eternal associate and expansion of Lord Shri Chaitanya Mahaprabhu. Lord Nityananda (Nitai) is none other than Shri Balarama, while Lord Chaitanya (Gaura) is Shri Krishna himself in the mood of his greatest devotee. Krishna and Balarama appeared on this planet 5,000 years ago, while Lord Chaitanya and Nitai appeared 500 years ago. Lord Gaura and Nitai are amazingly, and unlimitedly merciful forms of God, who have come to Earth to deliver the especially fallen souls (i.e, us!) living in the current time of quarrel and hypocrisy or Kali-yuga . Their lila (divine activities) are very deep and confidential and only the fortunate can enter into them or describe them–we will pray to do our best.
Our guru, Srila Prabhupada referred to Krishna as the Supreme Personality of Godhead. Godhead which generally refers to the nature of God, or the Holy Trinity in the West. However, it could imply other forms or aspects of the one spiritual substance of “Godhead”, which is how I think Prabhupada is using it. Although God is one, he is unlimited and inexhaustible, omnipresent and omnipotent, and we could add for our discussion, “omni-formed”.
Admitting our possible prejudice against God having many forms, let us look at the subject with an open mind, accepting at least the possibility. Even the idea of God having any form (which is thought as limiting) is difficult for many to accept, but unlimited forms? Why not? If God can do anything for his Divine purpose, why can’t he have or be one spiritual substance with diversity? And could his spiritual diversity have different aspects or forms? Although our material body is limiting, why does a spiritual form have to be a limitation?
We are a limited living being and we have many sub-personalities and sides of our nature, and people know us variously as well, so why not God? This is one way to understand the different expansions, forms and energies of God. If you are resistant to the idea, certainly you won’t be convinced by one blog or essay—and I am no scholar—yet you can know that some of the greatest philosophers of all time (although generally unknown) have argued convincingly about this subject of a personal God with many expansions, forms or incarnations to serve his divine will.
The Bhagavad-gita, and even more so, the Shrimad Bhagavatam and Chaitanya Charitamrita are meant for spiritually inclined thoughtful people who want to understand the truth from different angles of vision—and there are unlimited angles and perspectives of the One Supreme Truth. It is helpful to have a philosophical mind for understand the Krishna conscious philosophy—but not just material reasoning power alone.
This spiritual knowledge is simple for the open-heartedly simple, and difficult for the overly complex. Ultimately we will understand the Absolute Truth in its great complexity through a devoted, loving heart and not just by having a big brain. A devoted heart will incline the Sweet Absolute Shri Krishna and Balarama, or Shri Gaura and Nitai, to allow us to enter into their spiritual mysteries. Then all apparent contradictions will be solved through the logic of love.
Shri Chaitanya Mahaprabhu (the greatest master) is considered the most merciful incarnation of God because although the population today is considered spiritually unfit compared to previous ages, he is distributing the most profound and sublime gift of love of Krishna. We would expect the greatest gift to be given to the most qualified, but in the mood of causeless mercy, Lord Chaitanya and Nitai are giving the greatest spiritual love to the most unqualified in the most spiritual deficient age.
