What is considered a complete teshuva (repentance) for sin?

"One who has sinned and confessed his sin but has not really retracted is similar to one who has become ritually impure by holding on to a dead rodent and immerses himself in a mikveh to purify himself while still holding on to the dead rodent. He may immerse himself in all of the waters in the world but they will not purify him. Once he throws away the dead rodent, any mikveh will make him pure."

Rambam (Laws of Teshuva 2:3) uses this statement as a basis for his prescription for complete teshuva but uses the term "makes up his mind to abandon the sin" rather than "retracted" which appears in the gemara. This change may be understood in light of what he writes in the preceding paragraph where he mentions the different components of teshuva: Regret for the past, verbal confession of the sin, and a resolution not to repeat it are all mentioned, but he also adds the need to "abandon the sin".

Retraction and regret are certainly vital to the process of teshuva, but if one does not analyze the root of the sin which he has committed – the underlying weakness of character which caused him to go wrong – he is indeed like one who attempts to achieve purity while holding on to the dead rodent which will contaminate him over and over. It is like someone who takes an aspirin to cure an illness that requires surgery.

Throw away the dead rodent, urges the Sage, and get rid of your problem so that you can achieve a complete return.
