The main philosophy of yoga is simple: mind, body, and spirit are all one and cannot be clearly separated. Yet, there is a multitude of philosophical ideas that are helpful to explore the deeper dimensions of the body, mind, and spirit. Studying and understanding these ideas are essential to shift our view as ourselves as separate, to realizing the unitive state.
Yoga philosophy, similar to Buddhism, believes that spiritual ignorance creates suffering and binds us to the wheel of samsara (cycle of rebirth). The removal of our ignorance can take many different paths and techniques in yoga. Still, the central philosophical teachings of yoga revolve around the practice of mental discernment, detachment, spiritual knowledge, and self-awareness.
