Quote: "Three poisons or afflictions in Buddhism are ignorant, attachment, and aversion."
Yes. In Theravada Buddhism these are usually called the Three Unwholesome Roots.
"And what is the root of the unwholesome? Greed is a root of the unwholesome; hate is a root of the unwholesome; delusion is a root of the unwholesome. This is called the root of the unwholesome." http://www.accesstoinsight.org/tipitaka ... .ntbb.html
lobho akusalamūlaṃ, doso akusalamūlaṃ, moho akusalamūlaṃ — idaṃ vuccatāvuso, akusalamūlaṃ.
lobha is greed. Dosa is hatred, anger, aversion. Moha is delusion.
Sometimes raga (lust) or chanda (desire) are used in place of lobha.
Quote:"What is the difference between aversion and repulsion?"
Aversion is a mental reaction. Repulsion can be mental or physical, as when one
magnet repels another one. Revulsion is mental and is the same as hatred or aversion.
