The social institution known as varṇāśrama-dharma-the institution dividing society into four divisions or castes-is not meant to divide human society according to birth. Such divisions are in terms of educational qualifications. They are to keep the society in a state of peace and prosperity. The qualities mentioned herein are explained as transcendental qualities meant for making a person progress in spiritual understanding so he can get liberated from the material world. In the varṇāśrama institution the sannyāsī, or the person in the renounced order of life, is considered to be the head or the spiritual master of all the social statuses and orders. A brāhmaṇa is considered to be the spiritual master of the three other sections of a society, namely, the kṣatriyas, the vaiśyas and the śūdras, but a sannyāsī, who is on the top of the institution, is considered to be the spiritual master of the brāhmaṇas also. For a sannyāsī, the first qualification should be fearlessness. Because a sannyāsī has to be alone without any support or guarantee of support, he has simply to depend on the mercy of the Supreme Personality of Godhead. If he thinks, "After leaving my connections, who will protect me?" he should not accept the renounced order of life. One must be fully convinced that Kṛṣṇa or the Supreme Personality of Godhead in His localized aspect as Paramātmā is always within, that He is seeing everything and He always knows what one intends to do. One must thus have firm conviction that Kṛṣṇa as Paramātmā will take care of a soul surrendered to Him. "I shall never be alone," one should think. "Even if I live in the darkest regions of a forest I shall be accompanied by Kṛṣṇa, and He will give me all protection." That conviction is called abhayam, without fear. This state of mind is necessary for a person in the renounced order of life. Then he has to purify his existence. There are so many rules and regulations to be followed in the renounced order of life. Most important of all, a sannyāsī is strictly forbidden to have any intimate relationship with a woman. He is even forbidden to talk with a woman in a secluded place. Lord Caitanya was an ideal sannyāsī, and when He was at Purī His feminine devotees could not even come near to offer their respects. They were advised to bow down from a distant place. This is not a sign of hatred for women as a class, but it is a stricture imposed on the sannyāsī not to have close connections with women. One has to follow the rules and regulations of a particular status of life in order to purify his existence. For a sannyāsī, intimate relations with women and possessions of wealth for sense gratification are strictly forbidden. The ideal sannyāsī was Lord Caitanya Himself, and we can learn from His life that He was very strict in regards to women. Although He is considered to be the most liberal incarnation of Godhead, accepting the most fallen conditioned souls, He strictly followed the rules and regulations of the sannyāsa order of the life in connection with association with woman. One of His personal associates, namely Choṭa Haridāsa, was personally associated with Lord Caitanya, along with His other confidential personal associates, but somehow or other this Choṭa Haridāsa looked lustily on a young woman, and Lord Caitanya was so strict that He at once rejected him from the society of His personal associates. Lord Caitanya said, "For a sannyāsī or anyone who is aspiring to get out of the clutches of material nature and trying to elevate himself to the spiritual nature and go back to home, back to Godhead, for him, looking toward material possessions and women for sense gratification-not even enjoying them, but just looking toward them with such a propensity-is so condemned that he had better commit suicide before experiencing such illicit desires." So these are the processes for purification.
