interesting experiences

A yogi is required to be attentive to the digestive and eating routine of his body.

That is part of hatha yoga.

The Patanjali system lists it under the terms of asana and pranayama but the Hatha Yoga Pradipika gives more exposure to this attentiveness.

Materialistic people have a saying:

"Mind your own business."

In yoga that advice should be followed like this:

Be attentive to what happens in your psyche. Who cares about anyone else?
