"even if one has accepted the renounced order of life without sufficient knowledge, he should engage himself fully in hearing from a bona fide spiritual master to cultivate knowledge"

BG Chapters 13 - 18

This is the duty of a sannyāsī. If he is actually advanced and so ordered by his spiritual master, he should preach Kṛṣṇa consciousness with logic and understanding, and if one is not so advanced he should not accept the renounced order of life. But even if one has accepted the renounced order of life without sufficient knowledge, he should engage himself fully in hearing from a bona fide spiritual master to cultivate knowledge. A sannyāsī, or one in the renounced order of life, must be situated in fearlessness, sattva-saṁśuddhi (purity) and jñāna-yoga (knowledge).

BG 16.1-3, Purport:

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 possession 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 life in connection with association with woman. One of His personal associates, namely Choṭa Haridāsa, was 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 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.

The next item is jñāna-yoga-vyavasthiti: being engaged in the cultivation of knowledge. Sannyāsī life is meant for distributing knowledge to the householders and others who have forgotten their real life of spiritual advancement. A sannyāsī is supposed to beg from door to door for his livelihood, but this does not mean that he is a beggar. Humility is also one of the qualifications of a transcendentally situated person, and out of sheer humility the sannyāsī goes from door to door, not exactly for the purpose of begging, but to see the householders and awaken them to Kṛṣṇa consciousness. This is the duty of a sannyāsī. If he is actually advanced and so ordered by his spiritual master, he should preach Kṛṣṇa consciousness with logic and understanding, and if one is not so advanced he should not accept the renounced order of life. But even if one has accepted the renounced order of life without sufficient knowledge, he should engage himself fully in hearing from a bona fide spiritual master to cultivate knowledge. A sannyāsī, or one in the renounced order of life, must be situated in fearlessness, sattva-saṁśuddhi (purity) and jñāna-yoga (knowledge).

The next item is charity. Charity is meant for the householders. The householders should earn a livelihood by an honorable means and spend fifty percent of their income to propagate Kṛṣṇa consciousness all over the world. Thus a householder should give in charity to institutional societies that are engaged in that way. Charity should be given to the right receiver. There are different kinds of charity, as will be explained later on—charity in the modes of goodness, passion and ignorance. Charity in the mode of goodness is recommended by the scriptures, but charity in the modes of passion and ignorance is not recommended, because it is simply a waste of money. Charity should be given only to propagate Kṛṣṇa consciousness all over the world. That is charity in the mode of goodness.
