My older brother, Karl, made this for me. We originally just wanted an adjustable countdown timer using my bowl-bell as the sound to initiate and close the meditations. You can easily adjust the silence-duration anywhere from 1-60 minutes. The bell will ring, it will then be silent for your desired time duration, and then the bell chimes again at the end. This is how I use it, primarily. We then added 20 different guided meditations and excerpts of talks from my classes and workshops for those who would benefit from being led into the meditation. It’s a great little tool. Help my brother out. Enjoy!
