Technically speaking, the teachings of all Buddhas [a Buddha is a fully enlightened being] constitute of magnificent virtue since they cause devotion for the highest Truth and enlightenment – a life of pure wakefulness and awareness. They also cause innate joy and intelligence since they always consist of two-fold meanings that are easy to understand. Such teachings comprehensively propound the truly religious life that is rich of all great excellences.
An all-perfect Buddha’s teaching is usually unique in its application which has nothing much in common with others, given that it is glorious in its origin, glorious in the climax and glorious in its spirit and letter. As such, such wisdom becomes important in the termination of mind, body and spiritual delusions and obscurations for enlightenment; it’s a teaching that is pure by nature – pure from all taints and all accidental mucks.
The greatness of the teaching of a perfect Buddha is largely inconceivably subtle. The Teaching process usually proceeds with frequent repetition, for those who understand, through concise statements; and for those who understand through detailed expositions, using speech (and writing) and reasonable words that expound, deeply analyze and resolve various doubts.
This is true since proper teaching is best given expression through speech/writing. It goes ahead to make the subject known by use of most-reasonable words. With exposition of the truths, analysis and resolution of doubts respectively, it sets the subject forth, analyzes it and explains it. Such a noble teaching method makes use of frequent repetition and dissects the subject, setting it forth distinctively which results in the development of certainty. Then the skilled Buddha teaches it in brief to those who are endowed with brilliant faculties and thusly understand through succinct statements; he elucidates the teaching or truths fully for those who understand well through detailed explanations.
