My religion teaches me that I should, by my personal conduct, instill into the minds of those who might hold different views the conviction that cow killing is a sin.
What is Truth? A difficult question; but I have solved it for myself by saying that it is what the "voice within" tells you. All that I can in true humility present to you is that Truth is not to be found by anybody who has not got an abundant sense of humility. If you would swim on the bosom of the ocean of Truth you must reduce yourself to zero.
Nobody in this world possesses absolute truth. This is God's attribute alone. Relative truth is all we know. Therefore, we can only follow the truth as we see it. Such pursuit of truth cannot lead anyone astray.
"Be the change you want to see in the world"...and, if you can't be that change, then either get out of the way of the person who wants to be that change or support the individual with your financial resources.
