Meditation has many techniques. Similar to how people have many different motivations and programs when they have a regular gym practice.
Strength is different to agility is different to flexibility.
In more formal traditions the focus on breath (or similar) is to develop concentration/samatha/samadhi.
The focus on sensations is the insight/vipassana component, and often this is where the tension bubbles up to the surface. Keeping calm (equanimous) during this process can indeed be non-trivial!
It sounds like you have come to a practice very similar to a lot of the Burmese traditions of insight meditation, which is quite fascinating.
The one thing I really want is for someone to make it so I can use it in F#. Presumably it's possible given how the python bit is implemented under the hood?
It uses pyo3 to generate the bindings, so you would have to find a similar crate for F#/.NET and port the polars Python FFI to it. If such a crate does not exist, it will be even more work.
Thanks for the pointer. Augurs looks really promising.
If the matrix profile method was included it would be a nice alternative to the numba jit methods that are commonplace.
