The Importance of Meditative Concentration (Samādhi) of the Manas

Being able to concentrate single-mindedly on reading, contemplating, and working is all samādhi of the mind consciousness. But if the manas has no interest in this, is not settled upon reading and working, and does not apply mental attention to the content of the book, can the mind consciousness still be in samādhi? Absolutely impossible. If the manas is not in samādhi, the six consciousnesses cannot hope to be in samādhi; the six consciousnesses will inevitably scatter and wander like monkeys. Even though the mind consciousness continually applies focused mental attention, it is of no use—it will still be dragged about everywhere by the manas. Therefore, subduing the manas is the absolutely crucial point of cultivation. Hearing, contemplation, cultivation, and realization must all be implemented upon the manas; only then will all efforts not be made in vain, and results and karmic retribution are certain to follow.
