I've a thought. It's neither scientific, spiritual nor logical.
If God really cares about us, why should he/she 'drink' milk? There are so many people who really do not have money to feed themselves. The people who'll buy milk will continue to do so, hence if they 'feed' milk to God, then they'll possibly increase their quantity they buy. Now, it's the Cow or Buffalo is the loser. It's milk is meant for it's calf's maybe we can have it's surplus. Again why God encourage people to be deceived? Why can't he/she not 'drink' and hence save all the trouble?
Guys, what do you think?
