Kīrtanānanda: What was Arjuna's relationship to Kṛṣṇa?
Prabhupāda: Friendship. That is also... There are five kinds of relationship. Just like "God is great." That is simply feeling the greatness of God. Then, when he feels exactly how God is great, then naturally there will be an inclination to serve God. That is called servitude. First neutrality estimation... That is called śānta-rasa, neutral, no activity but simply appreciating, "God is great," simply appreciation. And then servitude. When the appreciation is complete, "Oh, why not serve God? He is so great. He is giving us so many things. Let me return something. Let me do some service of Him." Servitude. That is further development of the appreciation of the greatness of God. And then further development is friendship. Friendship means... Service means I ask you, "Please give me a glass of water." You give me. And friendship means you are thinking, "How my friend will be... Now he may be wanting a glass of water." So before asking me, if you give me, "I think you may require a glass of water," that is friendship. Friendship means feeling friend's welfare always. Suhṛt. Friendship is not simply chatting. Friendship means thinking, "How my friend will be happy?" This is friendship. Then that friendship, when further developed, that is parenthood. Just like parents, they have no other consideration. They want to see, "How my child will be happy always?" And further development is conjugal love, just like man and woman, male and female, that love. That love includes everything—that appreciation of greatness, that servitude of service, the friendship, then maternal love, and further, offering everything for the lover. That is most perfectional stage of love.
