वेगात घोषं पूरक भृंगनादम् ।
भृंगनादम् रेचकं मन्दमन्दम् ॥
योगिन्द्राणामेवमभ्यास योगात् ।
चित्तेजाता काचिदानन्दलीला॥
While doing Poorak quickly a humming sound like that of a male bee and while doing Rechak a hum sound like that of a female bee should be produced.
The person who practice Bhramari Pranayama regularly experience bliss.
