Mind that now it's a dead animal. Indian teachings fairly often talk down on it. What is meant may be blurred or unclear, though. That's a great flaw or worse, in case. What is wrong is selfishness in adults.
Selfishness is natural in children, and often dear.
To believe in the dictum of Ramakrishna and be mistaken, then, could bring you sufferings - and you should try to steer better than that. The cow suffers for other reasons than bellowing. That's one more point to remember. NOW YOU could feel greatly assertive that the Philistine king Melchezedek that blessed Abraham as a high priest of the Most High, knew how to get into God's heaven, but good proof is lacking. Try to ask for good evidence.
