SB 6.14.3
rajobhih sama-sankhyatah
parthivair iha jantavah
tesam ye kecanehante
sreyo vai manujadayah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In this material world there are as many living entities as atoms. Among these living entities, a very few are human beings, and among them, few are interested in following religious principles.
