We dream of being only light, because light is socially rewarded. But life is held together by a pair of opposites: protection and openness, accumulation and release, rest and mobilization.
The left half is cold and heavy, a security system that wakes first and scans reality for threats. The right half is warm and vulnerable: the memory of trust, the ability to stay in contact without armor.
Between them lies a boundary where the “I” stops being convenient and becomes whole.
