1. In Hinduism, the three surrounding protections or supports for the ātman (undying self): (i) sthūla-śarīra, the apparent body; (ii) sūksma-śarīra, also liṅgaśarīra, the subtle body, not evident to direct sight; (iii) kārana-śarīra, the body that supports the possibility of the attainment of bliss (ānanda). Because the ātman is thus protected, it can be carried from death to rebirth.
2. In Buddhism, the relics of the Buddha Śākyamuni, or of any other prominent Buddhist, usually preserved in a stūpa or pagoda.
