SiN

In a religious context, sin is the act of violating God's will by transgressing his commandments. Sin can also be viewed as any thought or action that endangers the ideal relationship between an individual and God; or as any diversion from the perceived ideal order for human living. To sin has been defined as "to miss the mark".

The word derives from "Old English syn(n), for original *sunjō... The stem may be related to that of Latin sons, sont-is guilty. In Old English there are examples of the original general sense, ‘offence, wrong-doing, misdeed'". The English Biblical terms translated as "sin" or "syn" from the Biblical Greek and Jewish terms sometimes originate from words in the latter languages denoting the act or state of missing the mark; the original sense of New Testament Greek ἁμαρτία hamartia "sin", is failure, being in error, missing the mark, especially in spear throwing;Hebrew hata "sin" originates in archery and literally refer to missing the "gold" at the centre of a target, but hitting the target, i.e. error.

In the Bahá'í Faith, humans are considered naturally good (perfect), fundamentally spiritual beings. Human beings were created because of God's immeasurable love. However, the Bahá'í teachings compare the human heart to a mirror, which, if turned away from the light of the sun (i.e. God), is incapable of receiving God's love.

Buddhism believes in the principle of karma, whereby suffering is the inevitable consequence of greed, anger, and delusion (known as the Three poisons). While there is no direct Buddhist equivalent of the Abrahamic concept of sin, wrongdoing is recognized in Buddhism. The concept of Buddhist ethics is consequentialist in nature and is not based upon duty towards any deity. Karma means action, and in Buddhist context, motivation is the most important aspect of an action. Whether karma done with mind, body and/or speech is called 'good' or 'bad', depends on whether it would bring pleasant or unpleasant results to the person who does the action. One needs to purify negative karma Four Satipatthanas to free oneself from obstacles to liberation from the vicious circle of rebirth. The purification reduces suffering and in the end one reaches Nirvana, the ultimate purification by realising seflessness or emptiness. An enlightened being is free of all the suffering and karmas, and will not be automatically born again.
