Sādhanā (Sanskrit: साधना; Tibetan: སྒྲུབ་ཐབས་, THL: druptap; Chinese: 修行; pinyin: xiūxíng) is an ego-transcending spiritual practice in Indian religions. It includes a variety of disciplines in Hindu, Buddhist and Jain traditions that are followed in order to achieve various spiritual or ritual objectives.
Sadhana is done for attaining detachment from worldly things, which can be a goal of a sadhu. Karma yoga, bhakti yoga and jnana yoga can also be described as sadhana; constant efforts to achieve maximum level of perfection in all streams of day-to-day life can be described as Sadhana.
