It does not matter what the sutta states if the sutta is not understood.
What you say is very true. Most people including DooDoot misinterpret the sutta. Does not use Dhamma Vicaya, 2nd factor of 7 factors of awakening, to investigate the 4 Frames of Reference.
The body meditation, It is not about meditating on corpses as some commentaries imply either. On Buddha's day a group of monks that meditated on similar stuff, became depressed and committed suicide.
If with wisdom you read the sutta DooDoot, it is not
about (being mindful (remembering) to not cling to body, feelings, mind & Dhamma)
either as you understood it, It is about using the
body, feelings, mind, and mind objects to bring suffering to an end
Satipatthana is called the ekayana, way to Nibbana. So it is logical to use 4NT and DO to assist the process. Now let us see, how do you meditate on the body wisely, if the end purpose is cessation of suffering, bring you to the third truth of
What does the body have that can teach us something dynamically?
It has sense bases. what is the issue with sense bases? when
objects impact those sense bases (Phassa) it creates feelings
of like dislike and neutral. This brings us to
second establishment. Meditating on feelings mean observing how feelings arise, prevail and fade away.
What is the problem with feelings?
it causes clinging
like dislike etc? what is the problem with clinging, we cling and react
. This reaction creates kamma, lengthens samsara
a whole jam of sankharas arise
, a big problem. Origination of volitional formations lead to more entanglement within paticca samuppada
, one place where we can stop DO, by interfering with these mental profusions
How to stop?
minimize the volitional formations. How do you minimize volitional formations? minimize feelings.
How do you minimize feelings? by minimizing contact or phassa
This is where sense restraint comes in, as taught in son's flesh. SN 12.63
Minimize contact with sensory world
keep it to the bare essential
See how the teaching is never one thing, meditator is using the entire teaching to enhance satipatthana, and bring an end to suffering, third noble truth
Knowledge of DO and purpose of satipatthana is not to arouse mental proliferation, and cause endless arguments, but to use these to end the mental proliferation.
I will continue with this later, for now think about it, meditate on it, without immediately reacting.
Imagine how magnificent this teaching is
Somewhere in the canon it says if you faithfully follow the sutta, you can achieve Nibbana in a very short time.
But then before we follow the system of the sutta and the Dhamma, we must really understand it, and be disciplined in body, mind and action.
PS How is discipline sharpened? via all factors of the eight, including Jhana.
