As I grew older I found a home in, "The Cloud of Unknowing". You might say that 'unknowing' is a way to tune the radio of your mind to static. Or that it is a way of turning off the voice in your head - your inner voice. And discover complete inner silence.
I discovered other ways to turn of the radio in my head, such as meditating in a warm bath for three hours. Falling in love turns off the radio. And listening to what trees and flowers have to say, plunges me into a delicious silence.
But most of I become silent, when I discover something new. I am like a Retriever pointing at a duck - my whole body becomes completely still and intent on the duck - on the new idea.
Recreational drugs don't help with this process at all, and I have a mild aversion to them.
