Bṛhaspaṭi Said:: These grasses unworthy of Yajñas should be discarded. One shall abstain from applying collyrium to the eyes, taking oil bath, applying scents and Sūtrapraṇayana (? sewing with threads). The holy rite should be performed with the Kuśa grass which grows again (when cut). One shall obtain the benefit of horse sacrifice. The following is the Mantra cited for offering flowers, applying scents and putting on ornaments.
