An experience teaches ably the good observer; but far from seeking a lesson in it, everyone looks for an argument in experience, and everyone interprets the conclusion in his own way.
It is the Path of the Good Mind which Thou hast manifested to me, O Ahura! Whereby the welldoers, in accordance with the teaching of the Spiritual Guides, acting in harmony with Truth alone, Shall pass onward to the assigned reward of which Thou art the bestower, O Mazda! This precious reward of Thine, O Mazda, Thou givest by way of the Good Mind, Thou givest to those who perform actions through knowledge and pure thought; who attempt for the progress and development of the world; fulfil God’s desire and try for the progress of God’s Will through truth and righteousness.
Food to a large extent is what holds a society together and eating is closely linked to deep spiritual experiences.
You have to grow from the inside out. None can teach you, none can make you spiritual. There is no other teacher but your own soul.
