Please forgive my total impertinence, but I strongly feel this needs to be said.
Some gurus/swamis are worthy of veneration, whilst others are just…well…‘meh’.
I mean, if I was at a satsanga and didn’t know all that much…then a ‘swami’ straight up told me that my nadis were impure and I needed to open my chakras and all that (without even explaining himself or at least starting me off in that direction)…I would go ‘WTF and who is this guy?’
Such concepts like ‘nadis’, ‘chakras’, ‘Kundalini’ and all that are for [B]advanced practitioners only[/B] (All, in my humble opinion, of course).
You wouldn’t just tell a yoga noob about these things.
That being said, the initial focus shouldn’t be about pranayama or even yoga for that matter.
Are you a vegetarian dear OP? do you smoke/drink alcohol? do you stay up late at night and wake up late in the morning? (my personal bad habit), do you indulge in a lot of sex? do you have bad thoughts about/towards others? Do you covet money/possessions?
Before you start doing [B]anything[/B], you need to get your body and mind into a ‘regime’ first and then you must start slowly, taking things one step at a time…
Do a few simple yoga postures for 10 minutes a day…meditate for 10 minutes a day, then add 5 minutes onto this every week, so at the end of 3 months, you are doing hatha yoga and meditating for an hour every day.
After a year, you can start incorporating pranayama and kriyas into your practice…again, starting off slowly and building it up until, in the end, you are spending about 3-4 hours daily on your sadhana and keeping your body and mind as pure as you can.
Then, after a few years, you can start to think about nadis, chakras and all the rest of it.
It just annoys me that a lot of noobs think they can pick up a book about the advanced precepts of yoga, or have a ‘guru’ tell them about it, and it automatically becomes, in essence, a ‘shortcut to enlightenment’. It does not work that way.
