Exercise and eating light is best IMO. I tend not to go overboard with stuff I won't be able to do forever. The older you get the more commitments a person has. I can no longer dedicate 2+ hours working out everyday. So, eat enough to obtain energy for work and maintain an exercise routine, but not too much that you end up gaining a pound here and there, or not eating enough so you end up feeling weak and fuzzy brained.
TV can jog on. Nonsense. Absorb good, high-minded thoughts and feelings and it will eventually reflect in your mindset. Glean bukwaas and you'll start chatting and thinking bukwaas, too. 😁
My cynicism and intimate knowledge of the Punjabi demeanour doesn't allow me to embrace this particular issue with as much positivity as others. I've seen where this type of narcotically-encouraged religiosity leads, and it's actually not as noble or as high-minded as it's being described here.
Each to their own. If it works for someone, then fair enough.
