Here we compare passions and desires to weed, on account of its evil effect exerted upon the congenital nature. Conversely, giving way to passions and desires other than cultivating congenital nature, and always ready to gratify greediness of organs which resulting in rooting out crop seedlings in stead of weed, you will always place yourself at the mercy of your destinies. The reasons leading to this conclusion lies in that congenital nature exerts its strength just only before the time when the heart busies itself with the action of continuously producing various ideas and thoughts. Your springing wisdom will fly high up and wild freely, your minds will become clear like an azure firmament. Heaven exists with no intention to make transformations and changes.
Earth endures with no purpose to produce all things.
So, man should pursue its distant course to Tao with no ideas and thoughts. Heart, as an endless resource, is always blamed for bringing about all distresses and bitterness in the region of existence. So a real practitioner constantly keeps aloof from worldly considerations, pursues its course with an indomitable spirit, and maintains his original pure character, while being oblivious of all things taken place, and forgetful of his existence, thus achieving ultimate state of communing with Tao. Great is the influence of changes and transformations regarding its power of enslaving the existence. Yet nothing is its capacity to employ the nonexistence.
