Why one is unable to approach a genuine Sadhu or a spiritual master even after he has spent time most of his life in false attempt of enjoying this material world?
It is said that the living entities are wandering in the universe, in different species of life and out of those only a fortunate soul can receive the seed of devotion (bhakti) by the grace of Krishna and Guru. Especially in this age of Kali, where people in general are unfortunate and easily misguided, and where pure representatives of the Lord are so few, it is very rare to come in contact with a genuine spiritual master. It requires a sincere desire and genuine endeavor on our part to find a bona fide guru, and along with our endeavor it also requires the mercy of the Lord.
The Supreme Personality of Godhead, Krishna, is worshipable as a father is worshipable for his son. He is the spiritual master because He originally gave the Vedic instructions to Brahma and presently He is also instructing Bhagavad-gita to Arjuna; therefore He is the original spiritual master, and any bona fide spiritual master at the present moment must be a descendant in the line of disciplic succession stemming from Krishna. Without being a representative of Krishna, one cannot become a teacher or spiritual master of transcendental subject matter
Krishna’s devotees relate to Krishna in various relationships; one might treat Krishna as a son, or one might treat Krishna as a husband, as a friend, or as a master. Krishna and Arjuna are related in friendship. As the father tolerates, or the husband or a master tolerates, so Krishna tolerates
