Moolmantra to open all chakras

I am so pleased with my new technique that I used this morning. I started saying Ek onkar and focused on the Seventh Chakra / Dasam Dwar. Then I moved my attention to the
3rd eye and said Satnam,
Karta purakh on throat,
Nirbhau Nirvair on Heart,
Akal Murat on Solar Plexus front side,
Ajuni on Secral front side,
Saibhang on Base
Then moved up towards the spine side of the chakra
Gurprasad jap on secral,
Aad Sach on Solar plexus,
jugad sach on Heart,
Hai Bhi Sach on Pineal Gland,
Nanak Hosi Bhi Sach on the point on the head that is one hand back from the seventh chakra.

I did this continuously for 15 minutes and enjoyed every bit of it from the first moment and no thoughts came in my mind. There was no time for thoughts an the focus was changing continuously but I enjoyed while I felt the vibration of each chakra corresponding with the shabad / sound.

I will try this method again to calm all thoughts. More interestingly I payed attention to each word in the mantra and realised how each word i said actually was mentioning the properties of that chakra and how God is different from the one that comes in the cycle of life and death. For example, I said Ajuni on the Sacrel chakra, the chakra representative of the birth cycle, Aad Sach on Solar Plexus, the centre of personal power and authority, Nirbhao Nirvair on heart, the centre which allows love and fear to prevail.
