Literally, a method of actualization, namely a meditation method for actualizing oneself as a Buddha-figure for which one has received empowerment. Performing a sadhana entails recitation of a ritual meditation text describing the self-visualization process and a complex series of further practices based on that self-generation, such as reciting mantras and making offerings. Synonymous with "self-generation" and "antecedent practice for realization."
