"The observer who is not adequate to the higher levels of significance will not know that they are being missed... Western-trained scientists must recognize that without specific preparation, there may be epistemological and paradigmatic limits to one's ability to comprehend and assess these disciplines, that scientific objectivity may need to be balanced (in at least some researchers) by personal experience and training, and that cautious open-mindedness to yogic claims may be a more skillful stance than automatic rejection of anything not immediately logical and comprehensible."
