Sickness of body is but natural with the changes their-in and on the sphere of age,
But sickness of mind or that Manas can be avoided as it is brought about through ignorance,
Ego, pride, feeling of dejection and low spirit is the diseases of mind manas track with,
Man can control manas through varying available subjects that align it with pitch of self to make human life meaningful and fruitful for ultimate gain.
May Lord bless all,
thanks Please
