The path to enlightenment, self-realization, moksha or spiritual liberation is essentially a pathway of Yoga. Specifically, this pathway of "Buddha Yoga" entails both mental meditation practice and inner cultivation of the Qi or Prana within your body via your willpower so that you can attain the first fruit of the spiritual path, which is an independent spiritual body that can leave your physical body at will. Buddha Yoga is also a pathway that requires you to polish your mind and behavior so that you can achieve the purity of virtue in thought, word and deed.
