In my experience, it doesn’t matter how loud/close I play the fields. The only other thing is whether the field is used for meditation purposes. In that instance whether loud/soft/earphones/speakers is individual choice.
For a definitive answer to this question (volume versus power) we have what SapienMed has said on countless occasions: volume does not matter as far as effectiveness of the field goes.
That said, everything else is conjecture. What people feel and think about how they personally experience the fields does not have anything to do with the original intention when they were created. People differ in energetic receptivity.
How you want it - it’s your experiment. But trying to telling people “it’s this way” or “it’s that way” is simply attempting to override their own experience of the journey.
If an environmental field has suggested play info, it is included in the thread, either in the OP or as an answer given to a direct question to the creator elsewhere in the thread.
Let’s face it, folks - this is magic , and there’s really (almost) no way to do it wrong. And yes, increasing one’s ability to be energy sensitive definitely adds to the journey in ways immeasurable, but as has been said before, just because you don’t feel it, doesn’t mean it’s not working.
