Perceiving the Truth of Natural Phenomena
The term “natural phenomena” consists of only two departments, namely, the form and formless phenomena. Although there is another kind of phenomenon, which is called nirvāṇa or nibbāna, it is not accessible to a worldly person — thus, we should ignore this for now. We should continue observing the form and formless phenomena until we realize the Three Marks of Existence. We must observe them until the truth of the Three Marks of Existence is revealed. Therefore, what is critical in our observance lies in perceiving the underlying Three Marks of Existence within the form and formless phenomena.
