Atiyoga is a philosophy that one's highest perfection or completeness is achieved through insight into the nature of primordial enlightenment, which is free from acceptance and rejection, hope and fear. As the second phase of the complete stage in Tantric practice, it is the point at which one can actualize the immediate causes of enlightenment, as well as the form figures or bodies of Buddha or other divine deities.
Atiyoga emphasizes the natural state, spontaneity and simplicity. It is thought to be a secret teaching or realization that an individual can attain through guided help from a guru. It is believed that upon reaching this “Great Perfection” through intense practice, meditation and spiritual revelation, troubling emotions and thoughts are liberated and one finds that fulfillment is produced without cause within one’s Self.
