Mind is present inside the body amidst the five sheaths(Pancha Koshas).The five sheaths are gross body sheath(Annamaya Kosha),Pranamaya Kosha(pertaining to the life force),Manomaya Kosha(mind sheath),Vijnanamaya Kosha(intellect sheath), andAnandamaya Kosha(Bliss sheath). Above the mind sheath isPrana(life force) and below it is discrimination power. Both of these are related to Fire. Mind is related to Water. The Moon is the presiding deity for the Mind. Hence coolness is its nature. Because of the presence of life force above and discrimination power below, the Mind melts and gets transformed into water. Water’s nature is to flow towards a lower level. It does not have the nature of flowing upwards. Hence the mind always wanders around the sensory and worldly pleasures. It cannot voyage towards the pure and higher stages. To divert the mind towards higher realms, spirituality is of utmost necessity. (My Dear Students, Vol 3, Ch 7, Jul 9, 1989. )
