Sri Madana Mohana, Sri Govinda and Sri Gopinatha

Vajranabha, the great-grandson of Krishna, first had three Deities of Krishna carved. He never saw Krishna, so they were carved from the description of Uttara, the mother of Maharaja Pariksit (others say it was Usha his mother). He had three different images carved, but none of them were perfect.

1. Govindaji resembled the face (Mukharabinda), 
2. Madana Mohana resembled the navel down to the lotus feet, and 
3. Gopinatha resembled the trunk of the body, from the navel to the neck. 

In Padma Purana it is said that to get the full vision of Sri Krishna, you have to visit and pay obeisances to all three Deities in a single day, while the sun is still up. Sri Govinda and Sri Gopinatha are now in Jaipur and Sri Madana Mohana is in Karoli, a small town in Rajasthan.

śrī rādhā saha śrī madana-mohana
śrī rādhā saha śrī govinda-charaṇa
śrī rādhā saha śrīla śrī gopīnātha
ei tina ṭhākura haya gauḍīyara nātha

“Sri Radha with Sri Madan-mohan, Sri Radha with Sri Govinda and Sri Radha with Sri Gopinath—these three Deities are the Lords of the Gaudiyas.”
ei tina ṭhākura gauḍīyāke kariyāchena ātma-sāt
e tinera charaṇa vando̐, tine mora nātha

“These three Deities have accepted the Gaudiyas as Their own. I offer my obeisance at the feet of these three Deities, they are My Lords.”

Three Stages of Devotional Service

In Caitanya Caritamrita Adi, it is that "In the process of establishing our relationship with Krishna there are three stages: sambandha, abhidheya, and prayojana. The three Deities-Madana Mohana, Govinda, and Gopinatha have very specific qualities.

1. Worship of Madana Mohana is on the platform of reestablishing our forgotten relationship with the Personality of Godhead (sambandha). In the material world we are presently in utter ignorance of our eternal relationship with the Supreme Lord; therefore it is best not to aspire for success in furtive activities or mental speculation, but instead simply to surrender to the Supreme Personality off Godhead. The perfection of life is simply to surrender to the Supreme. In the beginning of our spiritual life we must therefore worship Madana Mohana so that He may attract us and nullify our attachment for material sense gratification. This relationship with Madana Mohana is necessary for neophyte devotees. 
2. When one wishes to render service to the Lord with strong attachment, one then worships Govinda on the platform of transcendental service (abhidheya). Govinda is the reservoir of all pleasures.
3. When by the grace of Krishna and the devotees one reaches perfection in devotional service (prayojana), he can appreciate Krishna as Gopinatha or Gopijana-vallabha, the pleasure Deity of the damsels of Vraja.
