Following the instructions of the Spiritual Master

One must accept the words of an Acharya, a bona fide spiritual master, to clear the path for spiritual advancement.  This is the secret of success.  However, one’s guide must be a spiritual master who is actually an unalloyed devotee strictly following the instructions of the previous acharya without deviation.  Whatever the spiritual master says must be accepted by the disciple.  Only then is success certain.  This is Vedic system.
