The Bhagavad Gita says, Anityam Asukham Lokam Imam Prapya Bhajasva Maam Having reached this world which is temporary and full of misery contemplate on Me. This body is a den of dirt, disease-prone and cannot cross the ocean of Samsara. O mind, do not be under the delusion that body is permanent. Instead take refuge at the Divine Lotus Feet. As long as one is alive, one can aspire to lead a happy and healthy life.
Healthy body leads to healthy mind.
So, take proper care of your body and always contemplate on the selfless, pure, steady, Atmic principle. You are a member of society. Your welfare depends on the welfare of society. So, aspire for the well being of one and all. Eschew narrow-mindedness, cultivate broad feelings in order to experience bliss.
