“The seventh is ‘śauca’, that is, purification. Not outer śauca alone: inner śauca is what matters most, and that is the śauca of the antaḥkaraṇa. When there is neither rāga nor dveṣa, neither kāma nor krodha, and sāttvika, divine qualities shine forth, that may be called inner śauca. One must purify the body with water, Manas with Satya, the jīvātma with vidyā and tapas, and Buddhi with Jñāna.”
