Yogis and Siddhars possess enormous amount of inner experiential, spiritually scientific knowledge of life, its dimensions and human existence. Their experiential knowledge of spiritual dimensions and plexuses of the human body is far from the mainstream New Age ideas on "chakras", misinterpreted and borrowed from the yogic books. All the knowledge of those scriptures is encoded and can be only experienced through the natural process of Transmission, Kundalini ( Spiritual) Awakening and further evolution of Consciousness.
