As soon as you ask yourself, “What’s good for me?” and choose a path that leads to anything negative for someone else, you create and step into the world of evil. As soon as you intend an action that you think will benefit yourself while causing harm to someone else, you fall.
To intend good for both yourself and others, however, avoids evil completely.
What makes us intend harm to others? Harm already done to us. Where did it begin? In the earliest days of Homo sapiens, sentient humans.
The first true human being would have been born into a family of pre-humans. It is easy to imagine how the more sensitive human among the instinct-driven sub-humans would have experienced harm, or the perception of harm (even if the harm wasn’t intended), from its earliest days.
How ironic it would be if all the conflict and strife and war and power-mongering and killing in human history were the result of an original harm that was never intended as harm to begin with! Life is indeed poetic.
To be alone, a single human in a world of animals, even in your own family or household—this was apparently the first human’s first experience of interaction with others. All of human history since then has been the process of the Life within us striving to overcome the original “sin” done to it by its pre-human ancestors.
This means that the “false self” is a remnant of the animal nature within our psyche: the last problem we humans are to overcome in order to be fully human.
