Light in the soul works most powerfully. Light in the heart sometimes works; sometimes it does not. Light in the mind on very, very rare occasions works. Light works more satisfactorily inside the physical body and inside the vital than inside the mind. Light cannot work inside the mind precisely because the mind is revolting all the time against our own inner divinity. The miraculous power of light abides inside our heart of self-giving to humanity, to God the creation.
