" ... religious sādhanā, which both prevents an excess of worldliness and molds the mind and disposition (bhāva) into a form which develops the knowledge of dispassion and non-attachment. Sādhanā is a means whereby bondage becomes liberation."
- N. Batthacharya-
"Sādhana is a discipline undertaken in the pursuit of a goal. Abhyāsa is repeated practice performed with observation and reflection. Kriyā, or action, also implies perfect execution with study and investigation. Therefore, sādhana, abhyāsa, and kriyā all mean one and the same thing. A sādhaka, or practitioner, is one who skillfully applies...mind and intelligence in practice towards a spiritual goal."
