We have often heard the phrase “love of Godhead.” How far this love of Godhead can actually be developed can be learned from the Vaiṣṇava philosophy. Theoretical knowledge of love of God can be found in many places and in many scriptures, but what that love of Godhead actually is and how it is developed can be found in Vaiṣṇava literatures. It is the unique and highest development of love of God that is given by Caitanya Mahāprabhu.
Even in this material world we can have a little sense of love. How is this possible? It is due to the love which is found in the Godhead. Whatever we find within our experience within this conditional life is situated in the Supreme Lord, who is the ultimate source of everything. In our original relationship with the Supreme Lord there is real love, and that love is reflected pervertedly through material conditions. Our real love is continuous and unending, but because that love is reflected pervertedly in this material world, it lacks continuity and is inebriating. If we want real transcendental love, we have to transfer our love to the supreme lovable object—the Supreme Personality of Godhead. This is the basic principle of Kṛṣṇa consciousness.
In material consciousness we are trying to love that which is not at all lovable. We give our love to dogs and cats, running the risk that at the time of death we may think of them and consequently take birth in a family of cats or dogs. Thus love that does not have Kṛṣṇa as its object leads downward. It is not that Kṛṣṇa or God is something obscure or something that only a few chosen people can attain. Caitanya Mahāprabhu informs us that in every country and in every scripture there is some hint of love of Godhead. Unfortunately no one knows what love of Godhead actually is. The Vedic scriptures, however, are different in that they can direct the individual in the proper way to love God. Other scriptures do not give information on how one can love God, nor do they actually define or describe  what  or  who  the Godhead actually is. Although they officially promote love of Godhead, they have no idea how to execute it. But Caitanya Mahāprabhu gives a practical demonstration of how to love God in a conjugal relationship. Taking the part of Rādhārāṇī, Caitanya tries to love Kṛṣṇa as Rādhārāṇī loved Him. Kṛṣṇa was always amazed by Rādhārāṇī’s love. “How does Rādhārāṇī give Me such pleasure?” He would ask. In order to study Rādhārāṇī, Kṛṣṇa lived in Her role and tried to understand Himself. This is the secret of Lord Caitanya’s incarnation. Caitanya is Kṛṣṇa, but He has taken the mode or role of Rādhārāṇī to show us how to love Kṛṣṇa. Thus He is addressed: “I offer my respectful obeisances unto the Supreme Lord who is absorbed in Rādhārāṇī’s thoughts.”
This brings up the question of who Rādhārāṇī is and what Rādhā-Kṛṣṇa is. Actually Rādhā-Kṛṣṇa is the exchange of love. This is not ordinary love; Kṛṣṇa has immense potencies, of which three are principal: internal, external and marginal. In the internal potency there are three divisions:  samvit ,  hlādinī  and  sandhinī . The  hlādinī  potency is the pleasure potency. All living entities have this pleasure-seeking potency, for all beings are trying to have pleasure. This is the very nature of the living entity. At present we are trying to enjoy our pleasure potency by means of the body in this material condition. By bodily contact we are attempting to derive
