After the air element comes light, in the color spectrum heart is green.
The Green blade of grass converts the energy from the sun, creates oxygen. In the process of creation, after the ether element comes the air, Prana. Frequency of the heart is 528 hz (the middle note in music, the middle Chakra). The gross sound that can be pronounced for the heart chakra is 'haah' (as in heart). It is a subtle sound like a thought, so said within, and not spoken. यं, Yaṁ, is for the heart chakra, and also the Beej (seed) Mantra for meditation. Subtle vibrations in the ether element come first in creation. Let's look at the heart Chakra, called Anāhata, meaning unstruck. Each Chakra has a vibrational frequency related to it. There are many hidden truths to vibrations, and these secrets were encoded in the Vedas. 'If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.' - Nikola Tesla Chakras and Vibrations So if you drop below Beta you go into meditative states and even lower into expanded states of consciousness. Above 12 Hz to 30 Hz is Beta, which is our normal state of operating. The slower the brain operates the more capacity it has, so when it slows down to between 8 – 12 Hz (cycles) per second that’s Alpha state. And those are the expanded states of consciousness and awareness. The slower the brain operates the more we have access to it. The EEG goes from Beta, to Alpha to Theta. Once you become a vessel and use your voice, you are not only vibrating every cell of your being, but you’re also bringing your brain into a different brain wave frequency.
Once you atone and let go of that, you’re bringing yourself back into an attunement with higher vibration, and you are resonating differently.
Atonement really means to break free of the remnant vibrations that you have been living in, that’s labelled as sin, and all it is a lower frequency state. That’s what the words atonement and attunement have to do with sacred sound. That’s why sacred chanting is done, because then you are the vessel for those sacred sounds. When you entrain to these sounds then you become the instrument, your vibrations resonate throughout the body, elevates consciousness and can heal the physical body. Using the sacred sounds you can entrain your physical body, every cell of your being, to these sacred chants, which elevates consciousness. We can empower ourselves through the use of our voice. Sacred chants like the Vedic Mantras, or Gregorian chants, are in the rhythm of the underlying vibrations of our existence. There is a whole new realm of secrets about vibrations. Singing sacred songs and chanting has a deep and profound effect on our existence.
