Who Taught The First Teacher?

One devotional arc: Lord Vishnu silently kindles the light of sacred wisdom in Brahma's heart before creation begins as Guruh (The First Teacher). Even Brihaspati, preceptor of the gods, bows before Lord Vishnu's fathomless wisdom as Gurutamah (Teacher of All Teachers). Lord Vishnu Himself is the eternal sanctuary and dwelling place of all creation as Dhama (The Supreme Abode). While entire constellations revolve and wander through the cosmic night, Lord Vishnu stands at the unmoving center as the eternal Truth as Satyah (The Changeless Truth). Lord Vishnu measures all three worlds purely through the sacred power of an unbroken vow as Satyaparakramah (Whose Valor Is Truth). In the sacred Srirangam sanctum, Lord Ranganatha's eyelids rest closed in Yoga-Nidra, holding the universe safe as Nimishah (Eyes Closed in Yoga-Nidra). Even in divine repose, Lord Vishnu's unblinking lotus eyes watch over all creation with boundless love as Animishah (The Ever-Watchful Witness). While earthly blossoms wither, the celestial five-element garland upon Lord Vishnu's chest stays fresh forever as Sragvi (Adorned with Vaijayanti). Lord Vishnu generously bestows sacred speech and noble wisdom upon every earnest seeker as Vachaspatirudaradhih (Lord of Speech and Wisdom).
