Abhidhamma Dhātukathā (Abhidhamma Piṭaka Dhātukathā) is the high level of Buddha’s teaching. The content is about the body, physical contact, and the four elements (solid element, liquid element, heating element and air element) which formed the human body. While we are alive, we should consider that our bodies are impermanent, can change and perish finally. When we pass away, we cannot take our properties, lineage or relatives with us. Therefore, we must hurry to make merit, perform alms-giving, observe the religious precepts and do meditation which will be the benefit of making merit following us forever.
