As she has planted, so does she harvest; such is the field of karma. – Sri Guru Granth Sahib

My actions are my only true belongings. I cannot escape the consequences of my actions. My actions are the ground upon which I stand. – Thích Nhất Hạnh

O youth or young man, who fancy that you are neglected by the gods, know that if you become worse, you shall go to worse souls, or if better to the better… In every succession of life and death, you will do and suffer what like may fitly suffer at the hands of like. This is the justice of heaven. – Plato
