White Crow Yoga’s lineage is Thirumoolar’s Ashtanga Therapeutic Yoga. Thirumoolar (Tirumular, Thirumular, additional spellings) authored the Tirumandiram. Thirumoolar was a cowherd who had a burning love for the Divine. In 3,047 verses broken into 9 parts or Tantras, the Tirumandiram demonstrates a deep understanding of life and spirituality. His poetry talks about the unity of the Divine, the transformative power of bhakti or devotion, the efficacy of mantras and the vital connection between the breath and mind, sublime visions, ultimate God-realization, the serpent power of kundalini shakti, and the esoteric structures of the subtle body, such as the nadis and chakras.
