SĀDHANA or SADHANĀ (means of realization”), the spiritual path, especially of Tantra, that leads to perfection (siddhi). Although all authorities of Yoga subscribe to the view that we are inherently free, they also concur that in order to realize that native freedom, one must cultivate self-knowledge and an attitude of dispassion. In other words, one must live from a disposition that is analogous to inherent freedom, or enlightenment. This process of imitating the Divine (imitatio Dei) is the very essence of the spiritual path. See also ashta-anga-yoga, sapta-sādhana, shadanga-yoga, yoga-kritya.
