As one can derive fire from wood, milk from the milk bag of the cow, food grains and water from the land, and prosperity in one’s livelihood from industrial enterprises, so, by the practice of bhakti-yoga, even within this material world, one can achieve Your favor or intelligently approach You. Those who are pious all affirm this.
