Ch V wrote. “A thick cloud spreads out, covering the three thousand great thousand worlds, raining on them equally everywhere at the same time, its moisture reaching every part. The grasses, trees, forests and medicinal herbs - those of small roots, small stalks, small branches and small leaves, those of medium-sized roots, medium-sized stalks, medium-sized branches, medium-sized leaves or those of large roots, large stalks, large branches, and large leaves and also all the trees, whether great or small according to their size, small, medium, or large, all receive a portion of it. From the rain of the one cloud each according to its nature grows, blossoms, and bears fruit.”
“It is proper for you, Kalamas, to doubt, to be uncertain; uncertainty has arisen in you about what is doubtful.
Come, Kalamas. Do not go upon what has been acquired by repeated hearing; nor upon tradition; nor upon rumor; nor upon what is in a scripture; nor upon surmise; nor upon an axiom; nor upon specious reasoning; nor upon a bias towards a notion that has been pondered over; nor upon another's seeming ability; nor upon the consideration, 'The monk is our teacher.'
Kalamas, when you yourselves know: 'These things are bad; these things are blamable; these things are censured by the wise; undertaken and observed, these things lead to harm and ill,' abandon them.”
(The knowing that Buddha speaks of here ‘when you yourselves know’ is the knowing that arises as a result of direct experience of truth as it is moment to moment. Walk the path as suggested and from that you will come to know whether or not the path as suggested is correct. - beneficial in the beginning, middle and end.)
