The best description I found for getting to this “feeling-tone” is from Frank Kinslow’s book Quantum Living - briefly: he says to let your thoughts wander for 10-30secs, notice that thoughts appear to come from nothing (you really are not controlling them, they just pop in out of nowhere, out of nothing) then, ask yourself “I wonder what I will think of next?” and see what happens. In that space of asking you will notice that you actually “pause” and you sense that space of nothing. Now, if you do that repeatedly, you will notice the “pause” getting longer and you will sense a peace in the pause. Then, if you are able to focus on the “pause” and feel it longer, you will notice it becoming more positive - something he calls a “eufeeling” like a euphoric feeling. After doing it for a while, you should be able to get to that feeling place at any time, in any situation. For me, that “eufeeling” is everything, it’s where I choose to go. My suggestion is to start here, and play around with it and see where it goes for you.
