So nobody can be master. That is not possible. You'll find in this instruction, ekale īśvara kṛṣṇa āra saba bhṛtya (CC Adi 5.142). Only Kṛṣṇa is the master, and everyone is servant. This is our position, actual. But artificially we are trying to become master. That is struggle for existence. We are trying for something which we are not. We know this word, "struggle for existence," "survival of the fittest." So this is struggle. We are not master; still, we are trying to become master. The Māyāvāda philosophy, they also undergo severe type of austerities, penances, but what is the idea? The idea is that "I shall become one with God." Same mistake. Same mistake. He's not God, but he is trying to become God. Even though he has performed so much severe austerities, vairāgya, renunciation, everything . . . Sometimes they give up everything of material enjoyment, go to the forest, undergo severe type of penances. What is the idea? "I shall become one with God." The same mistake.
So māyā is very strong, that these mistakes continue even one is very advanced so-called spiritually. No. Therefore Caitanya Mahāprabhu touches the main point immediately with His instruction. That is Caitanya Mahāprabhu's philosophy. When Kṛṣṇa says the last word, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja . . . (BG 18.66), He is talking on the position, He is Kṛṣṇa, the Supreme Personality of Godhead. He is asking, demanding, "You rascal, give up everything. Just surrender to Me. Then you'll be happy." This is the last instruction of Bhagavad-gītā. Caitanya Mahāprabhu, the same Kṛṣṇa but acting as devotee of Kṛṣṇa; therefore He is speaking the same thing. Kṛṣṇa said, "You surrender," and Caitanya Mahāprabhu said that "Every living entity is the servant of Kṛṣṇa." That means he must surrender. Servant's business is to surrender, not to argue with the master or to claim that "I am equal with you." These are all fanatic, mad proposal.
