I hear om sound through my right ear but very distant and weak although clear☺. Please tell me how to spread this sound throughout my brain and then entire body.
Paramhansa Yogananda said that one is able to go deeper in the inner sounds, including AUM (OM) by deeper concentration and increased time in the AUM technique.
It’s helpful to spend time with the Hong-Sau technique that Yogananda taught, to aid in deepening one’s concentration, prior to tuning into the AUM technique itself.
It’s also helpful to chant AUM at the chakras, going up and down the spine, either silently or out loud. One of the things that many devotees have mentioned that can be supportive of being more in the experience AUM, is to listen to a recording of AUM.
I highly recommend a book by Joseph Bharat Cornell, titled AUM: The Melody of Love. This book takes readers on a journey into the deeper teachings of AUM and the blissful realizations that await those who access this expansive sound vibration.
All these suggestions can be very effective in tuning more deeply into AUM (OM).
Blessings on your spiritual journey,
