The Signs of meeting a Perfect Master
There are many signs for ascertaining that one has met a Perfect Master. The most significant of these is that one gets a first hand-experience, a living contact with Naam, the Light of God und the Voice of God.
The wish of the Master then, which, in fact, is the wish of the Lord, since the Master is merged in the Lord and there is no distinction between them, becomes the willing duty of the disciple. He then treads the Path of obedience and submission.
Your law is infinite, and nobody can fully comprehend it; he who meets a Master, treads the path ordained by Him.
Asa M5, 396-15
