The concept of the soul leaving the body varies widely across different cultures and spiritual beliefs, and there is no scientific consensus on the matter. Some traditions suggest it happens instantly at the moment of death, while others believe it may take time, often described in terms of moments or hours. Ultimately, the duration is largely a matter of personal belief and interpretation rather than empirical evidence.
