According to Rishi Carak, sleep is one of the three main sub-pillars that support our health (Carak Sutrasthan Chapter 11 verse 35). Our bodies need sleep when the mind and body are over-exerted after a long day of sensory overload. Good quality sleep occurs when the mind completely withdraws from the senses; if the mind remains engaged with sensory objects or perceptions, the quality of sleep deteriorates. But sometimes it is not easy to disengage the mind after a long or intense day of activities, even if we crave to have replenishing sound sleep. So what to do then?
