Kriyas are cleansing techniques used to purify the body and mind. Kriyas are also called Shat Karmas. Our ancient sages have prescribed processes to clean and remove the unwanted matter accumulated in the internal organs of the body through these yogic cleansing procedures. Commonly Neti, Dhauti, kapalabhati and trataka are practiced in day to day life. Laghu sankaprakshalana is also practiced to purify the digestive tract.
