The "Altar Sutra" is the only Buddhist classic named "Sutra" among the writings written by Chinese monks. Its core idea is "the heart is the Buddha" and "sudden enlightenment and enlightenment".
"The mind is the Buddha." The Tan Sutra expresses the true meaning of Buddhism's pursuit of liberation from the mind, and fully demonstrates the theory and practice.
"Sudden Enlightenment and Becoming a Buddha", the "Tan Sutra" firmly believes that all objects of worship in traditional Buddhism exist in people's hearts, and advocates that people should achieve self-realization, self-enlightenment and self-liberation. Those who can understand their own nature can achieve enlightenment and become a Buddha. While attributing Buddha nature to all minds and turning people into Buddhas, he advocates "seeking liberation in this world" and advocates the unification of entering the world and transcending the world.
