This document is about timing of death in astrology according to Mantreswara.
It states that the timing of one's death can be known from the condition of the 1st and 2nd lord of one's natal chart. The 1st lord shows one's life, health and vital energy while the 2nd lord shows family and wealth. If these lords are weak in the natal chart, one may face difficulties in areas related to them or untimely death.
It further explains that during the dasha period of the 2nd and 12th lord from one's moon sign, if the moon is afflicted, one's vital energy will reduce, indicating possible death.
