Translation
One who is engaged in devotional service has not the least fear in material existence. This is because the Supreme Personality of Godhead is the Supersoul and friend of everyone. One who knows this secret is actually educated, and one thus educated can become the spiritual master of the world. One who is an actually bona fide spiritual master, representative of Kṛṣṇa, is not different from Kṛṣṇa.

“Even if a brāhmaṇa is very learned in Vedic scriptures and knows the six occupational duties of a brāhmaṇa, he cannot become a guru, or spiritual master, unless he is a devotee of the Supreme Personality of Godhead. However, if one is born in a family of dog-eaters but is a pure devotee of the Lord, he can become a spiritual master.” The conclusion is that one cannot become a spiritual master unless he is a pure devotee of the Lord. One who is a spiritual master in accordance with the above descriptions of devotional service is to be understood as the Supreme Personality of Godhead personally present. According to the words mentioned here ( gurur hariḥ ), consulting a bona fide spiritual master means consulting the Supreme Personality of Godhead personally. One should therefore take shelter of such a bona fide spiritual master. Success in life means accepting a spiritual master who knows Kṛṣṇa as the only supreme beloved personality. One should worship such a confidential devotee of the Lord.
