The Abilities Required for Contemplative Practice

In practicing the Buddhist path and engaging in contemplative practice (vipaśyanā-caryā), one must have strong logical thinking ability; for logical thinking ability to be strong, one's train of thought must be good; for one's train of thought to be good, the mind must be clear; for the mind to be clear, one must have meditative concentration (samādhi). Cultivating logical thinking ability and possessing powerful powers of reasoning and discernment—this is the greatest wealth of wholesome dharma, the wellspring of wisdom, ever-flowing and never exhausted, until one attains buddhahood.
