Dheghemy says that the human should always endeavor to live in reality as it really is, instead of how he (or somebody else) would like it to be.
Most humen put up a wall between themselves and reality, and then interact with that wall instead of reality itself. The wall can be anything: religious delusion, addictive chemicals/behaviors, and so on; ANYTHING that walls off a man from reality.
Humen should engage with reality as reality presents itself, NOT as they wish it would. ALL addictive and perception altering substances/behaviors MUST be avoided in order to achieve this. A pure body follows a pure mind. The man should wake up unbeholden to the need for, say, the ingestion of a substance to “kickstart the day”. Likewise, he should be able to live his day without the need for a “pick-me-up”. Living in reality means that a man will be more able to make good decisions.
