A practitioner must not only practice self-cultivation but more importantly, cultivate his mind! Because only through introspection, to face up to and correct the inferiority of human nature ~ greed, slander, infatuation, slowness, doubt, evil opinions ... can sublimate the practitioner's own soul and further, crossing all beings. In addition to self-reflection and the reduction of human desires, the practice of spiritual practice also focuses on the dialogue with nature.
