Grhyasutras (Samskrit: गृह्यसूत्राणि) belonging to Kalpa of the Vedangas, as their title suggests, deal with grhya-karmani (गृह्यकर्माणि), i.e., the domestic activities. Written in the sutra style, these treatises systematically describe the grhyakarmas as practiced in their respective schools with utmost brevity. The number and order of these activities vary from one Grhyasutra to another. Since most of the ceremonies prescribed in the Grhyasutras are to be performed with the help of the Grhyaagni, i.e., grhya fire, the domestic fire, the description of the setting up of this fire finds an important place in the Grhyasutras.
