Why is dying in the presence of a saint considered a blessing rather than a tragedy according to the text?

Chapter 31 explains that dying in the presence of a saint is a supreme blessing because it transcends the normal experience of death. It is described as the "earning of life" and an act of great merit that redeems the creature from all its sins. The text states that when one leaves the body before a saint's gaze, it is not truly death but an experience of "Vaikuntha's (heaven's) bliss" and supreme joy, where even poison would become nectar. As verses 148 and 149 elaborate, such a death ensures there is no rebirth, and the individual is considered to have conquered the mortal world.
