The Rebbe taught, we must be like a goat – a goat doesn’t think! – it knows it has a job! – nor does a goat worry! (going to a goat farm – seeing thousands of goats, I can attest both are true) In other words, we are here to fulfill our Creator’s wishes from us (which are based on the Biblical wisdom of how to lead a moral, conscientious and kind life, and if one is not certain, one should ask a rabbi/mashpia or God-Himself (the mystical teaching is – the first thought after you ask God, is his reply) everything else, where you’ll get you cash etc. is all HIS capable job!
