Ruchira Avatara Hridaya-Siddha Yoga: The Divine (and Not Merely Cosmic) Spiritual Baptism in the Divine Way of Adidam (The Seventeen Companions of the True Dawn Horse)

Ruchira Avatar Adi Da Samraj has created a series of twenty-three books that He has designated as His "Source-Texts". Among these twenty-three books, there is a sub-series of seventeen volumes (called 'The Seventeen Companions Of The True Dawn Horse'), each of which offers His Wisdom relative to a fundamental aspect of true Spiritual life.

Ruchira Avatara Hridaya-Siddha Yoga (Book Eight of the "Seventeen Companions") is Avatar Adi Da’s instruction on the process of Spiritual Baptism and the phenomena of Kundalini Yoga.
