Those are wrong views, Gad.
I just looked at your last two Sutta references (AN 5.184 and MN 118.) If you read them carefully, you will be able to see that the Buddha instructed you NOT to do those things.
Does seeing a dead body give you “peace of mind”?
- No. It is repulsive for a layman to look at such sights.
- They can be used only in exceptional cases for those who have attained higher stages of magga phala.
Buddha Dhamma needs to be learned to cultivate wisdom, not to follow rituals.
P.S. Each of the ten items that you listed in your first post needs to be used with wisdom, not merely as a ritual.
- For example, regarding the list of ten times in your first post, let us take one: “6. Eating only from the alms-bowl (pattapindika)”
- This is discussed in the “Pattapiṇḍika Sutta (AN 5.190).”
- Most others are discussed in that series of suttas: AN 5. 181 through AN 5.190.
- One must first cultivate the mind and understand the perils of attaching to “worldly things.” Craving for the sensual pleasures CANNOT be removed forcefully by staying away from things one likes. But, of course, one must try to avoid sensual pleasures GRADUALLY with increasing understanding. See “Is It Necessary for a Buddhist to Eliminate Sensual Desires?“
