Mantras hold the power to dissolve all hopelessness and it helps one cross the river of samsara. In these verses, Rudra is invoked as the source and recipient of all mantras. Rudra is recognized as the truth of everything, Rudra is all light and all knowledge (Sat-Chit-Ananda), hence nothing is ever hidden from him. Rudra is the Vedas itself that reveal the truth hidden from me.
