Words of Wisdom and Comfort from the Bhagavad-gita

"As the embodied soul continually passes, in this body, from childhood to youth to old age, the soul similarly passes into another body at death. The self-realized soul is not bewildered by such a change." (2.13)
"For the soul there is never birth nor death. Nor, having once been, does he ever cease to be. He is unborn, eternal, ever existing, undying and primeval. He is not slain when the body is slain." (2.20)
"And whoever, at the time of death, quits his body, remembering Me alone, at once attains My nature. Of this there is no doubt." (8.5)
"Always think of Me and become My devotee. Worship me and offer your homage unto Me. Thus you will come to Me without fail. I promise you this because you are My very dear friend." (18.65)
