Unity is possible on the spiritual platform, not on the material platform. Material platform means “I am envious of you; you are envious of me.” Matsarata. Matsarata means matsarata para utkarsah asahanam[?]: when I cannot tolerate other increasing in opulence, I become envious. This is material life. Spiritual life is different. Spiritual life means if somebody has advanced in spiritual life, and somebody, one, he is still in the neophyte stage, he will eulogize, “Oh, how fortunate he is. He has advanced. He is serving Krsna in such a nice way. When I can get that position?” There is no enviousness. That is glorifying. That is the distinction between material life and spiritual life. [Material] life means enviousness: “How to kill you, how to stop you.” But spiritual life means to see you advancing, one becomes happy, “Oh, how fortunate he is.” This is spiritual life. Therefore spiritual life is meant for a person who is completely not envious. That is spiritual life. Paramo nirmatsaranam satam vastavam vastu vedyam atra. Dharmah projjhita-kaitavo ‘tra [SB 1.1.2]. This Bhagavata-dharma is meant for the person paramo nirmatsara, paramahamsa. He is not envious of anyone.
