The enigma of the soul: What is the truth behind its post-mortem departure?

In Hinduism, it is believed that the soul begins its journey to the afterlife after three days.
In Tibetan Buddhism, consciousness passes through several phases over a period of 49 days.
In some shamanic cultures, rituals are performed between the third and seventh days to accompany the “transition” of the spirit.
These beliefs, though diverse, share a common goal: to honor the transition, help the living accept loss, and give meaning to the mystery of death.

The mystery that links science and spirituality:
No scientific evidence validates the existence of the soul, but studies suggest that the process of death is far from instantaneous.

Between biology and belief, there remains a gray area — a space where science bows before the unknown, and where spirituality finds its full meaning.

What if the real mystery wasn’t when the soul departs, but how life continues to exist, differently, through what we leave behind?
