Sree Sree Guru Gaurangau Jayatah!
In Padma Purana it is mentioned –
guravo bahavah santi sisya-vittapaharakah
durlabhah sad-gurum devi sisya-santapaharakah
O Devi, there are many gurus who are expert in plundering the wealth of their disciples, but it is very rare to find a bona fide guru, who can remove the miseries of his disciples.
Getting a bona fide guru is not so easy. It is very difficult. A guru who desires worldly opulence is not an actual guru. You should realize the position of a guru. If you take shelter to a bona fide guru and surrender to him, then everything will come automatically. We should surrender to a pure devotee. Then those transcendental feelings will descend to us. Without the mercy of devotees it cannot happen. It cannot be attained from non-devotees.
