By Swami Harshananda
Sādhanacatuṣṭaya literally means ‘fourfold spiritual discipline of Vedānta’.
Works on Advaita Vedānta prescribes a mode of sādhana which has two stages. The first or the preliminary stage is called sādhanacatuṣṭaya or the fourfold spiritual discipline. These disciplines are:
- Viveka - discrimination
- Vairāgya - renunciation
- Śamādiṣaṭka - the group of six starting with śama or quietude
- Mumukṣutva - desire for mokṣa or liberation
- Sādhana means spiritual discipline.
