Singing Karaoke has offered me a glimpse of this. When I hit certain notes it is like opening the door to a higher realm/understanding.
On those occasions, when that feeling is particularly strong, people who hear me sing say "you should sing professionally".
So, it is something we can do physically to tune into our higher self.
The Beetles seem to have figured out the sound frequency, or possibly a combination of sound merged with the higher frequency of the being/soul.
