Spiritual science attempts to speak about non-sensory things in the same way that the natural sciences speak about sense-perceptible things...No one can ever deny others the right to ignore the supersensible, but there is never any legitimate reason for people to declare themselves authorities, not only on what they themselves are capable of knowing, but also on what they suppose cannot be known by any other human being.

For what lies inside of man is the whole spiritual cosmos in condensed form. In man's inner organism we have an image of the entire cosmos.

Every human being shall see in each and all of his fellow-men a hidden divinity... that every human being is made in the likeness of the Godhead. When that time comes there will be no need for any religious coercion; for then every meeting between one man and another will of itself be in the nature of a religious rite, a sacrament.

Each one of us has it in themselves to be a free spirit, just as every rose bud has in it a rose.

He who perceives in the spiritual world must know that at times Imaginations are assigned to him which at first he must forego understanding; he must receive them as Imaginations and let them ripen in his soul as such. In spiritual experience, much depends on a man having the patience to make observations, at first to simply accept them, and to wait with understanding them until the right moment arrives.

Geometry is knowledge that appears to be produced by human beings, yet whose meaning is totally independent of them.

When we raise ourselves through meditation to what unites us with the spirit, we quicken something within us that is eternal and unlimited by birth and death. Once we have experienced this eternal part in us, we can no longer doubt its existence. Meditation is thus the way to knowing and beholding the eternal, indestructible, essential centre of our being.
