अद्यप्रभृति षड्रात्रं रक्षतं राघवौ युवाम्।
दीक्षां गतो ह्येष मुनिर्मौनित्वं च गमिष्यति॥

adya-prabhṛti ṣaḍ-rātraṁ rakṣataṁ rāghavau yuvām
dīkṣāṁ
gato hy eṣa munir maunitvaṁ ca gamiṣyati

adya-prabhṛti = from today; ṣaḍ-rātram = to six nights from now; rakṣatam = should protect the sacrifice; rāghavau = [they said:] O descendants of Raghu; yuvām = You two; dīkṣām gataḥ hi = for he has undergone the preparation for the sacrifice; eṣaḥ = this; muniḥ = sage; maunitvam ca gamiṣyati = will become silent.

[They said:] O descendants of Raghu, You two should protect the sacrifice from today up to six nights from now. This sage will become silent for he has undergone the preparation for the sacrifice.
