Smiling away your troubles requires a clear conscience that harbors no insincerity.
Paramahansa YoganandaSpirit vibrated into matter; hence, both Spirit and matter exist. Matter, however, does not exist in the way that it appears to us. It exists as we see it owing to the delusive force of maya, which makes the indivisible Spirit seem finite and divisible to all appearances. Matter has existence in the same delusive way as does a mirage in the desert.
