In Accordance with the Dhamma (2)
Anudhamma Sutta  (SN 22:40)

Near Sāvatthī. “For a monk practicing the Dhamma in accordance with the Dhamma, what accords with the Dhamma is this: that he keep focused on inconstancy with regard to form, that he keep focused on inconstancy with regard to feeling, that he keep focused on inconstancy with regard to perception, that he keep focused on inconstancy with regard to fabrications, that he keep focused on inconstancy with regard to consciousness. As he keeps focusing on inconstancy with regard to form… feeling… perception… fabrications… consciousness, he comprehends form… feeling… perception… fabrications… consciousness. As he comprehends form… feeling… perception… fabrications… consciousness, he is totally released from form… feeling… perception… fabrications… consciousness. He is totally released from sorrows, lamentations, pains, distresses, & despairs. He is totally released, I tell you, from suffering & stress.”
