At what point does the fear of death become meaningless for a person, based on the philosophy in the Satcharita?

Based on the philosophy shared in Chapter 43, death becomes meaningless when one transcends identification with the physical body. The text describes death as merely the 'separation of body and senses' and a natural state for the body, not the soul. For those who 'remain after killing death' and 'place their feet on the head of Time,' the span of life is irrelevant. It is stated that for someone who has spiritually 'turned the body to ashes' even before the body physically falls, there is no fear of death. For such a wise person, death is like 'dust before him,' and life is understood as a mere modification of the body.
