A humble pouch of parched rice is all poor ill-dressed Sudama had to offer his sakha Lord Krishna. And Sudama tried as hard as he could but was unable to ask anything from his friend who was the king of the mighty Yadavas.
However, he returned home to find a palace standing at the spot where his poor hut had been, and his wife was bedecked with gold and there were cows in his gau-shala, and enough grain in his storage to feed him and his family for as long as they lived.
Bhakta-vatsal Krishna, the one who knows all, had responded to his bhakta's condition!
Whatever is invested selflessly in bhakti gives returns so handsome that you cannot compare it to any other worldly investment. And the rewards are not merely material. Invest in dharma because it continues to give us returns even beyond death. It is not for nothing that Pundit Chanakya says "Dharma mitram mritaschya!"
Jai Yadavakulbhushan Krishna ki! Jai bhaktaraj Sudama ki! Jai Bhaagvat vrinda ki!
