Shuddhi is Sanskrit for purification. In Hinduism it is a part of worship. It also sometimes refers to reverting to Hinduism after converting from Hinduism to another religion.

The socio-political movement, derived from ancient rite of shuddhikaran , or purification was started Arya Samaj, and its founder Swami Dayanand Saraswati and his followers like Swami Shraddhanand, who also worked on the Sangathan consolidation aspect of Hinduism, in North India, especially Punjab in early 1900s, though it gradually spread across India . Shuddhi had a social reform agenda behind its belligerent rationale and was aimed at abolishing the practise of untouchability by converting outcasts from other religions to Hinduism and integrating them into the mainstream community by elevating their position, and instilling self-confidence and self-determination in them.The movement strove to reduce the conversions of Hindus to Islam and Christianity, which were underway at the time .

In 1923, Swami Shraddhanand founded the 'Bhartiya Hindu Shuddhi Mahasabha' (Indian Hindu Purification Council) and pushed the agenda of reconversion peacefully, but ultimately created a flashpoint between Hindus and Muslims as it offended Muslim exceptionalists, who argued that Hindus, being dhimmis, do not have any rights to convert others to their faith unlike the Muslims, who are munim which was proved wrong later. The main point of contention was the reconversion Malkana Rajputs in western United Province Subsequently the movement became controversial and antagonized the Muslims populace to no end and also led to the martyrdom of the leader of the movement, Swami Shraddhanand in 1926. Gradually the movement faded away especially with the rise of nationalistic fervor during the Civil Disobedience movement of Mahatma Gandhi in the 1930s .

Kareena Kapoor (pronounced [kəˈriːnaː kəˈpuːr]; born on 21 September 1980), often informally referred to as Bebo, is an Indian actress who appears in Bollywood films.

She went on to play the lead female role in the Imtiaz Ali-directed romantic comedy Jab We Met (2007), for which she received the Filmfare Award for Best Actress, and the drama 3 Idiots (2009), which became the highest-grossing Bollywood film of all time.
