The Kabbalists were very against anger – in fact, we know the Jewish sages teach, that whoever gets angry, it is as if he has worshiped an idol… – for if we do get angry, it means that according to our belief, what happened was unfair!!! – but if we believe in God, “Does that mean, it is we! who determine reality?… – simultaneously, a person can become indolent – “if it’s up to God, why bother” – the answer is, it is our job to try (however when things work out not – we accept and move on – if you do this, you shall live)
