Doing sacrifice for getting gains in heaven leads may leads one to truth but,
One needs to perform duties without aspiring for a particular result may proves fruitful for both the worlds,
Vedas proclaim that one should do various sacrifices for merits to get fruits hereafter but with submission that never incur sins,
One needs to perform one's prescribed duty without aspiring for a particular fruit and it will take care of perpetual welfare at its ultimate mode,
May Lord bless all,
Thanks Please
