I think it is more useful and realistic to acknowledge that 'mind' is something that must always escape precise definition, on the basis that such things as definitions depend on mind, rather than vice versa. The instinctively naturalistic approach is always to try and locate phenomena in time and space, but it is the mind which provides that very framework. This is not only the province of Buddhism or paranormal research; philosophers such as Edmund Husserl have made the same point. But getting that point is very much a matter of a change in perspective - like a gestalt shift or something of that nature.
This is very interesting. Thank you. I will keep this in "mind" hehe.
