Rajas occupies a pivotal position in the depth-psychology corpus as the middle term of the guṇa triad — situated between the inertial darkness of tamas and the luminous equilibrium of sattva. The Sanskrit etymology, traced by Zimmer to ‘dust,’ ‘redness,’ and ‘passion,’ already signals its double valence: rajas is both the animating force of civilizational development and the source of compulsive, egocentric restlessness. Aurobindo treats it with systematic precision, defining it as the principle of kinesis, passion, and endeavour — the psychological power without which no initiative, no cultural achievement, no spiritual aspiration is even possible. Yet Aurobindo simultaneously insists that rajas, when relied upon as a final mode, produces only ‘rajasic eagerness, passion, disappointment, suffering, anger,’ and must ultimately be transcended. Easwaran, working from the Bhagavad Gita, personifies rajas with vivid socio-ethical concreteness: it is the engine of consumer civilization, environmental degradation, and the arms race — everything characterized by the grammar of ‘I, me, mine.’ Bryant and the Yoga Sūtra commentators approach rajas functionally, as the quality that must be progressively diminished in the citta so that sattva may disclose the distinction between puruṣa and prakṛti. The central tension across these voices is whether rajas is primarily a stage to be passed through or a force to be harnessed and sublimated — a tension that mirrors broader debates in depth psychology between the value of drive-energy and the necessity of its transformation.
