apostasy is the formal disaffiliation from or abandonment or renunciation of a religion by a person

United Nations Commission on Human Rights, considers the recanting of a person's religion a human right legally protected by the International Covenant on Civil and Political Rights:

The Committee observes that the freedom to 'have or to adopt' a religion or belief necessarily entails the freedom to choose a religion or belief, including the right to replace one's current religion or belief with another or to adopt atheistic views ... Article 18.2[5] bars coercion that would impair the right to have or adopt a religion or belief, including the use of threat of physical force or penal sanctions to compel believers or non-believers to adhere to their religious beliefs and congregations, to recant their religion or belief or to convert

There is no concept of heresy or apostasy in Hinduism. Hinduism grants absolute freedom for an individual to leave or choose his faith; on the Path of God. Hindus believe all sincere faiths ultimately lead to the same God

Hinduism conceives the whole world as a single family that deifies the one truth, and therefore it accepts all forms of beliefs and dismisses labels of distinct religions which would imply a division of identity. Hence, Hinduism is devoid of the concepts of apostasy, heresy, and blasphemy.
