[Letters of Helena Roerich in 9 Volumes - 5. 085]

"Precisely, it is the heart that knows the highest from the lowest; but when enfeebled and befogged, the heart itself will reside at the lowest level, where even the lowest will appear to be the highest.

And so, concisely and straightforwardly think about how to beautify the hearth of the world." [Leaves of Morya’s Garden II,301]

But his being is accustomed to egoistic thinking, and a most undesirable form of thought results. Two birds, flying in different flocks, cannot become united as one. It is necessary to exercise thought, not mentally, but with the fire of the spirit, until all disunity of thought disappears. Thought can have power only if it is monolithic. But each crack diminishes its power and also causes cosmic harm, by inducing dissonance into space. …We rejoice at diversity of thinking, but each thought must be pure as a diamond." [Agni Yoga, 345]
18. "With purity of heart one can sense the borderline that defines the influence of the creature and, sensing this boundary, correct an intended mistake. Later other danger signs will appear.

It is far better to discriminate in one’s actions than later regret the deeds." [Supermundane, 478]

The Thinker advised that at all times, while inhaling and exhaling, man should maintain himself in a state of purity." [Supermundane, 587]
23. "Man has no right to produce chaos and cause harm to the manifested world. You must remember and understand that each good thought begets goodness, and each dark thought is a cradle of evil." [Supermundane, 350]
24. "Do not think that superficial methods will produce complete results. The most essential is in the depths of one’s consciousness.
