[Heart, 334]

But how distant from lust is the feeling of the heart! The teaching about creative feeling will lead to an understanding of the creativity of thought." [Heart, 391]
11. "In all matters it is necessary to be guided by the straight-knowledge or the heart, there is no other measure.

[Letters of Helena Roerich in 9 Volumes - 2. 032]
17. It is necessary to "strive to develop spiritually, to awaken one's straight-knowledge, which is possible only with the purification of the heart and thinking from all prejudices and preconceived notions, namely with the expansion of consciousness and the striving of the heart to bring a feat. Of course, this program is available only to a minority, because few people understand and appreciate true beauty and its companion simplicity." [Letters of Helena Roerich in 9 Volumes - 2. 089]
