The present lecture examines personality (Svabhava) through Indian philosophy's four-dimensional model — Sharira (body), Manas (mind), Buddhi (intellect), and Atman (self) — supported by Bhagavad Gita verses on self-mastery, self-discipline, and emotional stability (illustrated via the Dhammapada's "unmoved rock" metaphor). It then centers on the doctrine of the three Gunas — Sattva (harmony/illumination), Rajas (action/dynamism), and Tamas (ignorance/inertia) — drawing on the Gita, Samkhya Karika, Hitopadesha, and Katha Upanishad to explain how these forces shape temperament, motivation, and behavior. The conclusion frames personality development not as external grooming but as an evolving elevation of consciousness, moving from Tamasic inertia through Rajasic striving toward Sattvic clarity and inner harmony.
