षडङ्गयोगान्न तु नैव शुद्धं मनोविनाशान्न तु नैव शुद्धम्। गुरूपदेशान्न तु नैव शुद्धं स्वयं च तत्त्वं स्वयमेव शुद्धम् ॥४८॥
The Atman cannot be purified through the practice of the six limbs of yoga, or through the annihilation of the mind, or through the instruction of a teacher. The Atman is the Reality Itself and It is Purity Itself.
