The subtle body is inherently closed for a significant reason. Once it is made open, the subconscious awakens which in turn emerges our karmas. Hatha Yoga is the most powerful in awakening the kundalini. It is also the most dangerous.
Once the nada is heard, slowly pierce through it until a softer sound appears. Focus on this new sound. Then go past the new sound and another one shall emerge. The nada is inside the mind only and the sound is to be heard in the mind only. We cannot create these sounds, they are already there. We have to attune our minds for the nada to manifest.
In a functional perspective, the goal of pranayama is to refine and make the natural breath healthier, balanced and more efficient. Pranayama purifies the Nadis so that the prana (life force) can freely flow through them, nourishing and recharging our vital organs. Further still, deep and meditative pranayama stills and calms the mind in preparation for the state of Samyama (concentration, meditation and absorption).
In this collection of lessons about meditation, I am sharing with you the powerful experience of Samadhi. The techniques I share here come from direct experience, most of them I filmed right after Samadhi itself. These are powerful techniques for spiritual healing and protection.
The euphoria attached to Samadhi is beautiful. It is many times addicting too. The student knows his limitations so he could easily get out. Once or twice in this lifetime is enough. To chase it could lead to a painful downfall. He needs to come back so he could share this wondrous spiritual journey.
