A root of self-harm lurks in our subconscious, it is the willing of thinking or wishing bad things on others. As comfortable and justifiable as this might seem at the time, there is a strong chance that such careless thoughts may come back to haunt us.
We have just shown the Universe the type of harmful things that have our approval and in doing so placed ourselves in the same boat. It’s ironic on all levels, thought, word or deed. What goes around comes around. To be useful in this life, think compassionately. Being generously thoughtful can do no harm.
