Skt.; derived from sādh, “to arrive at the goal” and meaning roughly “means to completion or perfection.” In Vajrayāna Buddhism, a term for a particular type of liturgical text and the meditation practices presented in it. Sādhana texts describe in a detailed fashion deities to be experienced as spiritual realities and the entire process from graphic visualization of them to dissolving them into formless meditation. Performing this type of religious practice, which is central to Tibetan Buddhism, requires empowerment and consecration by the master for practice connected with the particular deity involved. Part of this is transmission of the mantra associated with the deity.
