Answer: making heated milk offering twice daily
Notes: Between 1869 and 1873, Dayanand Saraswati established Gurukul (Vedic schools) in India. At the Vedic schools students were refrained from performing murti puja (worship of sculpted stone idols). Rather, they performed Sandhyavandanam (meditative prayer using Vedic mantras with divine sound) and agnihotra (making heated milk offering twice daily).
