The Study of Dharma Requires Consciousness to Investigate Jointly with Manas in Samadhi

Regardless of how many dharmas the consciousness knows, if the manas does not know, doubt will arise, and the mind will not feel settled and at ease. To resolve the doubts of manas and prevent it from doubting again, consciousness should not know things alone; both consciousnesses must investigate together. Once they come into contact with and realize the truth, both consciousnesses will know, and there will be no more doubt. To eliminate doubt and generate faith, it is essential not only to dispel the doubts of consciousness but, more importantly, to eliminate the doubts of manas.

Therefore, when studying the Dharma, consciousness should avoid mere speculation; instead, it should investigate together with manas in meditative concentration. The doubts of consciousness are shallow, while those of manas are deep. The deeper the doubt, the greater the sense of release once it is resolved, the greater the wisdom gained, and the more profound the transformation of body and mind.
