All the processes of creation and dissolution are true only from the scientific or practical standpoint but they disappear when the student inquires deeply into them. It is a matter of getting right understanding and then he sees they are mere thoughts or imaginations. A long training in right--that is, philosophic--thinking is required before the mind becomes habituated to such views. This is gnana yoga. After that he has to practise a still higher kind of yoga which goes on in the midst of activity and has nothing to do with meditation as ordinarily known. That ultimate path gives realization. He gets glimpses first, lightning-flashes, which through continued effort gradually become stabilized and finally merge into continuous knowledge of truth.
