According to Osho, right knowledge (praman) is a faculty of mind that, cultivated through concentration, meditation, contemplation, and prayer, discloses truth; its opposite, fueled by intoxication and sleepiness, breeds falsehood. After enlightenment (samadhi) the mind falls silent—there is neither knowing nor not-knowing, only pure being. Yet for communication an awakened one can briefly employ the mind’s right-knowledge center as a precise instrument, then rest again in silence.
Right knowledge is a truthful mind-tool you use when calm; after awakening you don’t need it, but you can still pick it up to speak with others.
