Buddhism uses hand gestures called mudras to convey important teachings and concepts. The document describes several mudras including: Vitarka Mudra which represents intellectual argument or debate; Dharmachakra Mudra used for teaching and turning the wheel of dharma; Bhumisparsha Mudra symbolizing calling the earth to witness; and Dhyana Mudra depicting absolute balance and meditation. Mudras are gestures that help communicate Buddhist principles in a concise visual way.
