How about this… ignore them! For the most part.
Acknowledge them only in the most minor way “Oh hey, vibrations, great…” then just continue doing what you were doing before they occurred.
Let me explain. Vibrations should ONLY ever be considered a signpost experience/sensation. They are one of those sensations you will experience during your practices which tell you that you’re on the right path. Basically, they’re a signpost that reads, “Keep doing what you’re doing, because you’re doing it right!!”.
However, what most people (especially new people) end up doing is the COMPLETE OPPOSITE!!! They end up stopping the method/exercise they were doing which CAUSED the vibrations in the first place and then focus entirely on the vibrations instead of what they were doing!! It’s like they’re walking happily down their path towards Astral Projection, then someone pokes then with a vibrating stick and then walk off the path in order to investigate that stick. Well, you’ve just stopped walking towards projecting. Understand?
So, the signpost DOES NOT read, “Stop what you’re doing and focus completely on me!”… there’s no better way to KILL your experience than to stop what you were doing to focus on the vibrations.
When you experience those vibrations, they’re only telling you that you’re doing things right. That’s it. Just give them a mental nod and continue walking calmly down the path you’re on. You now know you’re on the correct path, BUT you still need to continue walking down that path if you’re to actually project. So, in order to continue walking down that path… just keep doing what you were doing which brought on the vibrations in the first place.
You’re so close.
