舍利子 (shèlìzǐ): śarīra; bead-like relics found…

From Sanskrit śarīra (body/remains). In Buddhist tradition, crystalline pearl-like objects sometimes found among the cremated ashes of advanced practitioners are venerated as evidence of spiritual attainment. Famous examples include the Buddha's tooth relic 佛牙舍利 (Fóyá shèlì) housed at temples in Beijing and Sri Lanka.

舍 here is shè (4th tone, 'building/monastery'-related, derived from 'to dwell'), not shě ('to give up'). Same character, different reading by sense — Buddhist context fixes it as shè.
