Krishna expands the menu of sacrifices to cover every possible human aptitude. He lists four distinct paths practiced by disciplined seekers who hold strict vows (yatayaḥ saṃśita-vratāḥ): 1. Dravya-yajñāḥ: The sacrifice of material wealth and possessions. 2. Tapo-yajñāḥ: The sacrifice of severe physical and mental austerities. 3. Yoga-yajñāḥ: The sacrifice of mystical practice (like Ashtanga). 4. Svādhyāya-jñāna-yajñāś ca: The sacrifice of rigorous self-study and the pursuit of transcendental knowledge.
