TThis is what you experience when you have a NDE;
The first thing one realises, when you die, or slip into coma, is that though the body is mortal, the atman is immortal. The atman leaves the body through the agnya chakra and consciousness remains after death. Post death consciousness is more vivid than in real life. One can see colours, unseen during earthly life. One can hear the holy sound OM and the gayatri mantra in afterlife. Consciousness survives death and souls experience an awesome sense of love, connectedness and peace. Just as gravity attracts the physical body downwards, The Hindu cosmic trinity, Brahma, Vishnu and Mahesh combined with the divine feminine (Saraswati, Mahalakshmi and Durga) appear as a beam of dazzling light, brighter than the brightest light on earth, pulls one's consciousness through a divine tunnel. Your whole life flashes infront of you starting from your birth on a cinemascopic screen, where one's soul experiences, the emotions encountered in our soul's earthly journey.
