The days have been compared to the soldiers of Candavega. Night is generally a time for sex enjoyment. Days are considered to be white, and nights are considered to be black, or, from another point of view, there are two kinds of nightsblack nights and white nights. All these days and nights combine to pass away our span of life and everything we manufacture for sense gratification. Material activity means manufacturing things for sense gratification. Scientists are conducting research to find out how we can satisfy our senses more and more elaborately. In this Kali-yuga, the demoniac mentality is employed in manufacturing various machines to facilitate the process of sense gratification. There are so many machines for ordinary household activities. There are machines for washing dishes, cleansing the floor, shaving, clipping hairtoday everything is done by machine. All these facilities for sense gratification are described in this verse as sarva-kama-vinirmitam. The time factor, however, is so strong that not only is our span of life being expended, but all the machines and facilities for sense gratification are deteriorating. Therefore in this verse the word vilumpanti (plundering) is used. Everything is being plundered from the very beginning of our lives.
