This booklet contains an explanation of aspects of traditional Vedanta practice in the light of nondual Self-Knowledge and Self-inquiry.The four requisites are: discrimination, detachment, the six essentials, and the desire for Liberation. The six essentials are peacefulness, self-control, renunciation or nondependence, endurance or fortitude, faith or conviction, and profound, concentrated, formless meditation. The book will help the spiritual aspirant understand the original significance of the requisites, put them into practice, and thus dissolve the illusion of ignorant dualism and its consequent bondage and suffering, and realize the true natural state of the Self, Brahman, which is of the nature of Being-Consciousness-Bliss.
