Krishna — Gita: The Power Between the Eye-brows — Third Eye — The Seat of the Soul:
9 He who remembers the Poet, the Creator, who rules all
10 things from all time, smaller than the smallest atom, but upholding this vast universe, who shines like the sun beyond darkness, far far beyond human thought; and at the time of his departure is in union of love and the power of Yoga and, with a mind that wanders not, keeps the power of his life between his eye-brows, he goes to that Spirit Supreme, the Supreme Spirit of light.
11 Hear now of that Path which the seers of the Veda call the Eternal, and which is reached by those who, in peace from earthly passions, live a life of holiness and strive for perfection.
12 If when a man leaves his earthly body he is in the silence of Yoga and, closing the doors of the soul, he keeps the mind in his heart, and places in the head the breath of life,
Sound — The Word
13 And remembering me he utters OM, the eternal WORD of Brahman, he goes to the Path Supreme.
