99Hz Mirror (Weighted)

99Hz is a low, hypnotic frequency a mirror that draws attention deeply inward.
It is ideal for grounding, clearing, and mesmerizing the system into a deep state of focused calm concentration.
This frequency holds the essence of the number 9, symbol of completion, return, and transcendence.
In numerology it carries the 1 + 8 polarity, echoing the spiritual principle of unity (1) reflected through the infinite (8).
Used with intention, 99Hz becomes a gateway to inner silence, trance states, and lucid embodiment.

Ways to Use
Single Fork Use:
Play on the legs, hip bones, stomach area by playing this frequency on top of a crystal lying on the stomach.
Make the spine or pubic bone vibrate to support deep grounding and release of tension.
Excellent for pre-sleep, emotional decompression, or transitioning into trance states.
The low vibration makes it particularly effective for the body deep relaxation and somatic work.
 
Dual Fork Use:
Use two 99Hz forks in stereo to create a deep, immersive bass effect, ideal for vibroacoustic meditation, sound baths, or rituals.
Slightly detune one fork to create a slow binaural beat, facilitating theta or delta brainwave entrainment for subconscious access and healing.
 
Important Note:
As with all direct physical interaction, ask for consent when touching or placing a tuning fork on another’s body. Share necessary information in order to receive informed consent prior starting a session. Announce placements of the interaction on the body and hold space with clarity and care with open communication giving agency supporting autonomy at all times through out the session. 

How to ask for consent:
- Announce placements by pointing at the locations the tuning fork will be placed on the body prior the session starts.
- Express that if any of these points are uncomfortable for them they are welcome to express it and the session can be interrupted or adjusted accordingly.
- Give the agency for them to interrupt the session at any time if they wish so, or if they have any immediate needs or wish to express themselves.

The use of tuning forks in a deep somatic recalibration can bring to the surface unpleasant memories, feelings and thoughts. It is essential to hold space for them in the pace that supports their wellbeing and ideal integration process.

In Ultra Heaven Cosmology;
99Hz is the Mirror Gate, the tone of deep inner stillness where all waves settle into clarity. It teaches that inner stillness is not the absence of movement, but intentional presence.
This fork can be used in the closing phase of journeys, to seal the field and return to the Self with depth and grandiosity.

Colin / Ground Tactics highlights all frequencies as primordial information, vibration as the source of creation and sound the genesis of all languages existing before human language existed and even before life itself. He emphasise sound potential to in-form values, not only sound but multi dimensional values (numbers, frequencies, geometry, emotional values, mental & symbolical values...) elevating the awareness of ourselves and our environment, subconsciously directing how do we react and relate to what we feel and hear.

By embracing the exploration of frequencies, you are initiating the transformative self recognition process, engaging in our soul purpose of being Students of Love, reconciling with our nervous system intentionally, preparing the way for all other harmonic codes of transformation to lead us to wholeness.
