1. "Hence, the knowledge of the spirit is such a powerful guide, for it will always lead to the foundations of Existence." [Hierarchy, 324]
2. "…The clearer the earthly consciousness, the quicker the awakening of the spirit." [Supermundane, 304]
3. "Expansion of the consciousness will establish the knowledge of the spirit..." [Leaves of Morya’s Garden II, 362]
4. "The most subtle reciprocity is through spirit-understanding. The force of the reciprocity of spirit-understanding is incomparable to anything." [Fiery World III, 38]
5. "No one can draft a boundary line to limit the knowledge of the spirit." [Fiery World II, 269]
6. "Allow the spirit to aspire. Exercise discretion in accordance with your spiritual awareness. Ask yourself, “How does the spirit want to act?” This stage of “spirit-knowledge” is important. As you approach it, it seems as if the spirit is very far away; but this is only apparently so, for in reality the spirit is knocking hard. It is important to grasp the spirit’s knowledge and take a direct course of action—you should act in the way that you wish to. It is better if you can apply this approach on details rather than risk using it on a massive scale." [Leaves of Morya’s Garden II, 120]
7. "No clairvoyance can compare with the knowledge of the spirit. Truth can come through this knowledge. Only by this path comes understanding of the needs of the time... Ancient priests considered the knowledge of the spirit to be the highest manifestation, for it could not be attained by any physical exercises but consisted of accumulations from former lives." [Leaves of Morya’s Garden II, 313]
8. "The actions of the spirit are lightning-fast and are connected with the work of a fiery thought. You can just know without resorting to the usual methods of cognition." [Facets of Agni Yoga 1956, 329]
9. "The judgment of the spirit is harsh and impartial." [Facets of Agni Yoga 1961, 280]
10. "Spiritual understanding or spiritual comprehension is needed, that is, knowledge of the spirit… Intellect... is based on external feelings. Insight into the future is not available to it. It cannot instantly solve a complex mathematical problem, as Kovalevskaya did, and it cannot see life in Distant Worlds. The knowledge of the spirit, and only it, will raise a person to the next stage of evolution. And the intellect will serve the spirit as a tool for a good master ... in order to merge with him to go further to the heights of knowledge of the world." [Facets of Agni Yoga 1962, 161]
11. "... The knowledge of the spirit is alien to ordinariness and when confronted with it loses its clarity and simplicity. Hence the constancy of the struggle between earthly knowledge, or earthly wisdom, and the knowledge of the spirit, or insight into the realm of what really exists." [Facets of Agni Yoga 1962, 114]
