Genuine realization is invariably the product of many contributing factors

The manas has shallow wisdom because the dharmas that the manas takes as its object are too extensive, making it unable to attentively and meticulously discern and deliberate (manana); moreover, its own afflictive habits are heavy, and it constantly grasps at conditions without being able to concentrate. However, in a state of meditative concentration (samādhi), the manas can maintain focus to the greatest extent, thereby increasing the power of its deliberative wisdom; the mind consciousness can also more easily engage in direct perception/valid direct cognition, and the likelihood that the manas accepts the conclusions of the mind consciousness's direct observation is higher, making it easier for the result of realization to appear.

In summary, realization is necessarily the product of many factors coming together, including the condition of meditative concentration, the mind consciousness's direct observation, the manas maintaining focus, and the manas deliberating with power—only then can the manas finally confirm. Among these many factors, meditative concentration is the prerequisite. Without meditative concentration, the mind consciousness cannot easily engage in direct observation, the manas cannot easily maintain focus, and the manas will not readily accept the mind consciousness's observation. Therefore, in the process of realization, meditative concentration plays a crucial role. The prerequisite for meditative concentration is keeping the precepts and keeping the mind from restless movement; the prerequisite for keeping the precepts well is having merit. None of the bodhisattva's six pāramitās can be lacking.
