The great master Padmasambhava said,
Even if my view is higher than the sky,
The attention I pay to my actions and their effects is ﬁner than ﬂour.
When your realization of the emptiness of all phenomena becomes as vast as the sky, your conﬁdence in the law of causality of actions will grow proportionately, and you will become aware of the real signiﬁcance of your conduct. In fact, relative truth is inseparable from absolute truth. The profound realization of the empty nature of all things has never led anyone to believe that positive actions do not create happiness and negative actions do not cause suffering.
