In the tantric yoga philosophy, two key concepts are that of prakasha and vimarsha–light and reflection. Prakasha is the fullness of the light of consciousness itself; vimarsha, the reflection of the light that is our own individual recognition of the light of consciousness in ourselves. The sweetly mysterious joy we get in seeing reflections in a puddle is the reminder we are given of the pulsing dance between the light and the reflection of the light, neither of which we can know without the other.
