As explained in that post, “Patthana Dhamma – Connection to Cause and Effect (Hetu Phala)“, a tree will die if the transportation of nutrients is cut-off by girdling.
In the same way, the samsaric process is stopped by cutting off the “nutrients” that feed it.
This can be stated in many different ways: removing lobha, dosa, moha is at the root; that will automatically remove the other 3 root causes of alobha, adosa, amoha; see, “Six Root Causes – Loka Samudaya (Arising of Suffering) and Loka Nirodhaya (Nibbana)“.
Removal of dasa samyojana, 12 types of akusala citta, 7 types of anusaya, or 4 types of asava gets to the same result: “Conditions for the Four Stages of Nibbana“.
Comprehension of Tilakkhana will lead to that final result of permanent release from suffering, Nibbana. All above will be completed.
Furthermore, Satipatthana/Anapanasati is the way to get there, once Tilakkhana are comprehended.
– Of course, one must get rid of the 10 types of micca ditthi, before being able to comprehend Tilakkhana.
