“The purpose of meditation is to make our mind calm and peaceful. If our mind is peaceful, we will be free from worries and mental discomfort, and so we will experience true happiness. But if our mind is not peaceful, we will find it very difficult to be happy, even if we are living in the very best conditions.” –Kelsang Gyatso
This is a good explanation and reason for meditating. I would only add that meditating could be described as focusing the mind, and focusing allows the mind to become calm. With love, RP
