Sadhana; 成就法 (珠他); Tibetan: སྒྲུབ་ཐབས (druptap); Wylie: sgrub thabs; Sanskrit: sādhana;

Sadhana is a method of accomplishment, an exercise or practice to achieve various spiritual objectives or goals. A sadhana is also a practice text to meditate to visualize, recite mantras and make offerings. A typical tantric sadhana structure involves a preliminary part, including the taking refuge and generating bodhichitta; a main part involving visualization of a deity and recitation of mantras; and a final part with a dedication of merits to all sentient beings. In lower tantras, practitioners invoke the deity in the sky in front, while in higher tantras, practitioners arise in the form of the deity.

成就法通常分為三階段：前行部分包括皈依和生起菩提心，正行部分涉及觀想本尊和念咒，而結行部分則是將功德回向眾生。
