There is a reality called jealousy, it is what is the source of all malevolence

Quite simply speaking, it goes like this, God created man and man was jealous of God

God took an offering from hevel and kayin was jealous of hevel

All evil comes from jealousy

The emotion of jealousy is the devil himself, hence it was the satan that caused Adam to get jealous in the first place Come to think of it, the sin of Chava was jealousy, but the sin of Adam was lust

Anyway, the bottom line is, that the antidote to jealousy which is a perception of unfair lack, is the perception of unfair gain, hence to not be jealous which is the most vile part of every human and as our sages teach, man is jealous of everyone and everything beside their child or student, one must quite simple be cognizant that life is really a continuous undeserved gift which is the meditation, ein oid milvadoi, all continuously renews from God’s love!
