Today is the auspicious day of Ekadashi. In Vaishnav culture, we fast every fortnight for religious reasons but there is a really good scientific reason behind this fasting tradition. You should refrain from eating and give your digestive system some rest every fortnight to cleanse your body.
Couple of years back, I came across this beautiful poem. I do not know its author but the wordings are so true.
Useless are your pilgrimages galore
If your thoughts remain as before
And useless is a whole month’s fast
If your mind continues its merry repast
Of what use is your sacrificial fire
If it doesn’t burn your base desire
And God will surely set your prayers aside
If you visit a temple and then show pride
Your pilgrimages, fasts, worship, sacrifice
All these will never suffice
If your conduct continues to remain the same
For then these are not holy.
They’re just a game!
