Within us there is a world of subtle energies, that constantly influence our state of being. Understanding their nature is to come into alignment with this vast inner world. Ancient yogic mapped out our spiritual anatomy by dividing these energies into the Pancha Prāṇa and five Vāyus: Prāṇa, Apāna, Udāna, Samāna and Vyāna. Becoming aware of their presence is an enormous resource for the Sadhana and for all of life, because in their specific characteristics they have the power to alter, shift and transform.
