Helen,
Most all of what you have said also resonates within me and how I practice Reiki.
Reiki is foremost for us and our own clearing, balancing and hopefully healing. The clearest channel is the best channel of energy. When we become this then with intent, compassion and love, we can help others when they request it.
And to the original post about singing bowls, no I don't use them but have been around them in the past and love their sound. I also love the voice of the drum, rattle, and chimes with deep tones.
All blessings,
Donna
