It is about knowledge
“The highest education is that which does not merely give us information but makes our life in harmony with all existence.” -Rabindranath Tagore
Yogi/Guru Gorakhnath regards a thorough knowledge of the Cakras, the Adharas, the Lakshyas, the Vyomas, or Akasas, as well as of the Nadis and the Vayus, as essential for any success in the path of yogic discipline and the attainment of perfect freedom from all forms of apparent bondage and
limitation and sorrow and perfect mastery over all the phenomenal forces governing the individual body and the cosmic system. He instructs the truth seeker in the path of yoga to discover these within their own bodies, to concentrate their attention upon them and to practice particular forms of discipline in relation to them, with the ultimate view of realising the self-revelation of Siva and His Sakti in each and all of them. But it is quite evident from his instruction that he does not conceive the m as merely physical or even vital parts of the physical body.
They are not purely physiological concepts based on what are ordinarily recognized as scientific proofs. He is not concerned with the science of physiology, but with the science and philosophy of yoga. The individual body is not conceived by him as a purely material body (as physiological sciences ordinarily conceive it), but as a spiritual entity revealed in a material form, and as capable of being liberated from its material limitations.
