Lord of Death (Yama) is as omnipresent as Lord Siva! Yama is associated with the body (deha); He cannot affect the individual soul (jiva). Siva is associated with the individual soul, but He won’t allow the body to subsist for any length of time. The body is the essential vehicle for the individual soul to understand its real nature. Still who knows when the body may become the target for the attention of Yama? The individual soul, burdened with this destructible body, must grasp the above-mentioned caution and be all-eager to merge in Siva! No single moment that is passed by can be turned back. People usually delay doing some things; yesterday’s till today and today’s till tomorrow. For the tasks of spiritual discipline, there is no yesterday and no tomorrow. This very moment is the moment! The minute that just elapsed is beyond your grasp; so too, the approaching minute is not yours! Only those who have this understanding engraved in their heart can merge in Siva.

- Prema Vahini, Ch 40.
