The wastage of time can be definitely arrested.
1. Sleep is a rejuvenating factor. Even a machine has to be given rest. For the maintenance of this body-mind-complex, rest is essential. Rest is a must. The body, the mind and the intellect have immense potentialities. They can render tremendous work if they are properly used. We have no idea of the hidden capacities they possess. The intellect is to be used as a servant and it should not be allowed to be the master; because it can render positive arguments to support even your weaknesses. So, rest is necessary to keep the machine efficient. But, we have to decide how much sleep is necessary for this body. Only that much should be taken, so that we save the remaining time. This is time gained and therefore an increase on the revenue side of time.
2. Have enough exercise and asanas to keep the body fit, so that it works efficiently and smoothly and does not get any ailment. In the absence of a fit body, we suffer from ailments and sufferings in which time is lost again. We arrest this wastage of time and save the time as well as the energy, which otherwise would have been lost. This is again a gain. No suffering and no wastage means an abundance of energy, vitality and enthusiasm. You are Dhrityusahasamanvitah.
