Used together, the weighted 54 Hz and 72 Hz tuning forks are a powerful grounding/earthing tool that focuses on realigning your brainwave activity. The binaural beat of the forks balance the right and left hemispheres of the brain (entrainment) permitting mindless chatter and the ego to be quieted. They can be used anywhere on the body to assist with relaxation and promote a calming nature.
Use these forks when you feel a lack of connectedness, unable to focus or concentrate, and feel the need to ground yourself.
