We invoke Lord Ganesha, the remover of all obstacles, the one who is considered the most auspicious. This is an ancient chant taken from Rig Veda (2.23.1). Rig Veda is one of the four canonical sacred texts of Hinduism. Rig Veda is a collection 1028 of Vedic Sanskrit Hymns and 10,600 Verses.

2: You are the Wisdom of the Wise and the Uppermost in Glory,
3: You are the Eldest Lord (i.e. ever Unborn) and is of the Nature of Brahman (Absolute Consciousness); You are the Embodiment of the Sacred Pranava (Om),
4: Please come to us by Listening to our Prayers and be Present in the Seat of this Sacred Sacrificial Altar.
