The cobra breath is nothing but a fancy renaming and repackaging of the Kriya Yoga techniques They just use a fancy name (cobra breath)so they can make thousands of $$$ teaching it and telling people to keep it a secret.
You can easily find all of these techniques online, search "Kriya Yoga by Ennio Nimis pdf" (without quotation marks) and you will find a PDF that contains all of these techniques with instructions.
Keep in mind that it's much inferior to the techniques from ToZ though. It's also not the fastest way to raise your kundalini, as it's indirect.
I see and you have my thanks.
Now I've one problem since I thought cobra would be helpful in merging Ida, Pingala and Sushumna and stimulate sexual energy at the same time.
I wanted a breath that I could cover these and could be practiced discreetly during the day.
And I found this description of the cobra breath method here on the ToZ forum but still thought something was a bit off and so I went to verify before doing it.
Can you please look at this and tell me if you recognize it?
Is this the kriya yoga you were talking about and if not what breath is this?
The last point ressemble how you usually end the reversed sitkari breath
Cobra Breath
1. Lean your back against a wall or chair. You can optionally practice Sat Kriya posture.
2. Put your tongue on your palate. Slowly contract your anal muscles.
3. Inhale. As you inhale, feel the energy coming up from the base of your spine. It should move towards the back of your head.
4. Keep your tongue on your palate as you exhale.
5. Exhale slowly, making a hissing sound like a snake.
As you exhale you should contract the facial muscles around your chin and lips as if you were laughing.
