In the Yoga philosophy, it is said that Brahma, which is the essence of knowledge without the second, becomes the Individual Soul only when invested with Ignorance. In the Yoga Scriptures, therefore, both Brahma and Individual Soul are spoken of.
बुद्धमप्रतिबुद्धत्वाद् बुध्यमानं च तत्त्वतः। बुध्यमानं च बुद्धं च प्राहुर्योगनिदर्शनम्॥
