We know that God is Omniscient. Saints are the manifest form of God. They have qualities related to spiritual practice, but most Saints do not have knowledge about worldly matters that is useful in spiritual practice. To my knowledge, H. H. Pande Maharaj is the only Saint who is an exception to this rule. Without thinking, He can instantaneously provide new perspectives on any subject like art, sculpting, spreading Spirituality, classes on raising children in a sattvik (spiritually pure) way, satseva related to collecting offerings through advertisements.
