Yoga is union. It is a way of living in the eco-system with the human body. Yoga is not a practice, yoga is a life. The need for a spiritual path arises due to the thirst for total liberation. This total liberation is not mental, it is physical. So naturally, one needs to prepare the body, to reunite with life. Yoga becomes a very important role in that process. The Inner Yoga brings total liberation, the union of the human body to the cosmic realm. That way it becomes a spiritual path, rather than just a practice.
Inner Yoga is a technique to experience the natural state of being, beyond the human perception. It is a naturalization process revealing our uniqueness and helping us to practically enter into an awakened state.
