We often talk about the "wisdom of the heart", that "one must feel with the heart", that "the heart will not deceive"... And we really feel with the heart, our heart shrinks, melts, trembles, becomes heavier. Prishvin writes: "Be afraid to think without the participation of the heart." The elders teach: "to stand with the mind in the heart," "to immerse the mind in the depth of the heart."
