6. "Outside the window a call was heard. One worker brushed it aside: “Don't disturb me, I’m busy!” Another one promised to come but forgot. A third came after work, but the place was already empty. A fourth began to quiver on hearing the call, and setting down his tools, went out at once: “Here I am!” This is called the tremor of sensitivity. Only this tremor, illumined by awareness day and night, leads to the knowledge of the spirit. …If you are able to avoid stifling this tremor of sensitivity, good for you!" [Leaves of Morya’s Garden II, 330]
7. "But still, sometimes the pain inflicted on loved ones hurts the nearest heart very much. And it must be refined to such an extent that it responds sensitively to any pain around.

Suffering for people near and far, for the whole world unspeakably sharpens the receptivity of the heart." [Facets of Agni Yoga 1965, 854]
8. "The most difficult art is the art of creating relationships between people. No art requires the development of such patience and such refined sensitivity.

[Letters of Helena Roerich in 9 Volumes - 4. 076]
9. "One needs to cultivate thinking intensely in order to attain sensitiveness." [AUM, 466]

Even in the best instances, it must be developed, or more precisely, called forth from the depths of consciousness." [Supermundane, 573]
11. "…The most important thing is the education of the heart, and moreover from an early age. It is necessary to plant the seeds of love for nature and compassion and sensitivity to all living things." [Letters of Helena Roerich in 9 Volumes - 7. 104]

15. "Under the existing conditions of earthly life various pains may be expected, but certainly these sufferings occur, not as a result of sensitiveness, but by reason of abnormality of life. If there were an uninfected atmosphere, then sensitiveness would be seen as a true good; but people prefer to pollute the planet..." [Brotherhood, 208]
