What are the four prohibitions for members of Khalsa?

Members of the Khalsa, a collective of initiated Sikhs, adhere to the Four Prohibitions known as the "Four D's": they must abstain from consuming tobacco, alcohol, and other intoxicants, as well as from engaging in adultery. These prohibitions are intended to promote a life of discipline, purity, and commitment to spiritual and moral values within the Sikh faith. By following these guidelines, Khalsa members strive to embody the principles of Sikhism and maintain their dedication to their faith and community.
