In Class 2 we study Sūtras I.5–I.11, where Patañjali maps the mind’s movements. He first divides thoughts into kliṣṭa (clouding, obstructive) and akliṣṭa (clarifying), then names five vṛttis: pramāṇa (reliable knowing), viparyaya (mistaken knowing), vikalpa (imagination/constructs), nidrā (sleep), and smṛti (memory). David grounds each one in daily life—the judgment calls we make, the rope-snake error, the power and pitfalls of imagination, plain sleep versus samādhi, and the way memory paints the present. The point isn’t to shut thinking down, but to recognize what we’re doing when we think, so identification loosens and the seer can stand a little more free.
