Service in Kṛṣṇa consciousness is, however, best practiced under the able guidance of a spiritual master who is a bona fide representative of Kṛṣṇa, who knows the nature of the student and who can guide him to act in Kṛṣṇa consciousness. As such, to be well versed in Kṛṣṇa consciousness one has to act firmly and obey the representative of Kṛṣṇa, and one should accept the instruction of the bona fide spiritual master as one’s mission in life.
