In plain words
To act without Ajñāna is the special mark of humanness
The day we take up strength of body, power of mind and a vow in the form of the word, that is the triad. We must make bodily, mental and spiritual action, these three, one. This oneness gives us divinity. Divinity is not somewhere far away. Just as the air around us is there without being seen by the eye, so the divine, though it is around us, in you, with you, above you, below you, around you, wherever one looks, is not seen by you. What is the reason? You have not developed the eyes that see it. People run after outer objects, after the creation, but do not try to run after the Creator. You hang back from longing for God, who created everything. You run after this small and trifling creation. Seeing a mirage, the deer think it is water and run after it; finding no water and quenching no thirst, falling into hopelessness and despair, at last they give up their lives. In the same way we wander after possessions and vehicles, after physical pleasures and worldly passions, and since in the end these neither bring lasting Ānanda nor give true happiness, we too at last, like the deer, lose our lives in hopelessness and despair. This can never be the special worth of humanness. Mā-na-va: "mā" means Ajñāna; "na" means without; "va" means acting. Only when we recognise and act on the truth that acting without Ajñāna is the special mark of humanness is this education fruitful. I hope you will recognise this truth.
The principle of Brahman is equally present in the ant and in Brahmā
Along with learning, we must blend in divinity. When we take up bodily matters, we must recognise botany well. This body is like a tree. Kinsmen and friends are like the branches and twigs. Feelings are like the flowers. The fruit of the mind is like the fruit of the tree. The sweet juice inside the fruit is virtue.
