namaste,

Recently restarted my practice. I have a question about the breath that I am struggling with.
When in meditation (or trying to get into the state) is the breath supposed to be deep and long for instance coming from the belly to the nostrils or shallow (sukshma?) from nostril to center of brows?

The reason why I am asking is that I have heard and read opposing suggestions on this. Possibly that's due to practioners using different techniques for meditations. But wondering what's the right ways.

In my case, the normal breath is shallow but if I start paying attention to it, it becomes deep. Maybe subconciously I start breathing deeper because I am paying attention to it?

Any suggestions/ thoughts would be much appreciated.
