"Lightness and weightiness are both linked to a philosophy of life. They are choices in life. Heaviness can be the embodiment of a sense of responsibility, the expression of maturity, the result of profound meditation or the emanation of a search for meaning in life. Weightiness, however, may also lead to a feeling of oppression, when it is felt as a burden, an unbearable burden. Then time has come to let loose and things can finally lose their gravity. ['The unbearable heaviness of being']"
