sarvātmanāśrita-pado yadi nirvyalīkam
te dustarām atitaranti ca deva-māyāṁ
naiṣāṁ mamāham iti dhīḥ śva-śṛgāla-bhakṣye
The unalloyed devotees of the Lord know the glories of the Lord in the sense that they can understand how great the Lord is and how great is His expansion of diverse energy. Those who are attached to the perishable body can hardly enter into the realm of the science of Godhead. The whole materialistic world, based on the conception of the material body as the self, is ignorant of the science of God. The materialist is always busy working for the welfare of the material body, not only his own but also those of his children, kinsmen, communitymen, countrymen, etc. The materialists have many branches of philanthropic and altruistic activities from a political, national and international angle of vision, but none of the field work can go beyond the jurisdiction of the misconception of identifying the material body with the spirit soul. Unless, therefore, one is saved from the wrong conception of the body and the soul, there is no knowledge of Godhead, and unless there is knowledge of God, all advancement of material civilization, however dazzling, should be considered a failure.
