satipatthana is closely akin to the 4 buddhist jhanas, latter being a more elegant version of the practice. It is gotta be, right? I agree with Polak, not in the details, though.
There is this unusual sutta in the Satipatthana samyutta, that the theravadin seems to have missed, but not the Sarvastivadin. The sutta is unique, called Origination SN 47.42
First establishment refers to the origination of the body due to origination of nutriment, and cessation of body is due to the stopping of food channel.
The one who wants to take a short cut to nibbana, can do this using “Son’s flesh” only.
It is the most dramatic sutta in the entire Buddhist canon, yet many fail to grasp its importance. Why did the compassionate SammaSambuddha, resort to a shocking simile. The nightmare of parents crossing desert feeding on jerky made of own son’s flesh, infant? A mother would faint, at the suggestion, right?
If only I could, I mean not feed on meat made of dried son’s flesh, but that is exactly what I do, when I give in to sensual pleasures.
There is this hidden factor to the metaphor…
In the comprehension of physical food, passion for the five strings of sensuality are also to be comprehended, the sight, the aroma, the taste, the tactility, just the thought of food, right?
There is no fetter bound by which a disciple of the noble ones would come back again to this world— when passion for the five strings of sensuality is comprehended. I read this in the buddhist literature, whoever the commentator who thought it up is a genius, she connected the dots, 'cause this is exactly what Buddha meant by this simile.
It applies in all situations, six senses, right? the unholy world of sensophere, which the holy has to negotiate.
A short cut to Nibbana, that requires steel of resolve.
