The mystic understands that illuminated souls, guiding souls, are on earth today too. They were not only in the past; they are here now also. Were there none on the earth now, how could illumination be continued? It is the present that is the best, not the past. What is present today will be the past tomorrow, so the mystic does not lose the opportunity of recognizing the spirit in the present as well as in the past. The Sufis use such terms as Wali, Nabi, Ghous, Rasul, Qutub. But names do not matter, though the grades are necessary. The influence of one soul may be felt in a village, of another in a county, of another in the whole country.
