"The transition from tenseness, self-responsibility, and worry, to equanimity, receptivity, and peace, is the most wonderful of all... shiftings of inner equilibrium... of... centre of energy... [T]he chief wonder... is that... it so often comes about, not by doing, but by... relaxing and throwing the burden down. This abandonment of self-responsibility... antedates theologies and is independent of philosophies. Mind-cure, theosophy, stoicism, ordinary neurological hygiene, insist on it as emphatically as Christianity... and it is capable of entering into closest marriage with every... creed. Christians who have it... in... 'recollection,' and are never anxious about the future, nor worry over the outcome of the day. Of Saint Catharine of Genoa... 'she took cognizance of things, only as they were presented to her in succession, moment by moment.' To her holy soul, 'the divine moment was the present... and when the present moment was estimated in itself and in its relations, and when the duty... in it was accomplished, it was permitted to pass away as if it had never been, and to give way to... the moment... after.' Hinduism, mind-cure, and theosophy all lay great emphasis upon this concentration of the consciousness upon the moment at hand."
