Master Kuiji entered meditative concentration for several thousand years in a past life. If the manas is not settled, how could he remain in samādhi for thousands of years? Within that samādhi there were no six consciousnesses; if the six consciousnesses were present, one could not remain in concentration for long. The meditative concentration of the non-Buddhists is also very powerful—they can remain in samādhi for eighty thousand great kalpas, all with the manas in concentration.
