Crystallizing the root chakra

[Infinite Unity]

Great posts so far!

I always saw red ray as that centre tied to one's survival and very existence, therefore blockages show up as a desire to not want to be alive - leading to chronic depressions and in extreme circumstances - suicidal idealisation. Therefore to strengthen the red ray is to affirm the opportunity for life and excitement for third density experience.

I always thought clearing blockages was a mental exercise, yet some people claim to also do this via physical exercises, like yoga. Can someone explain how these two methods fit with one another?  

The physical and metaphysical are inseparable. You work your body, through your mind. So in other terms the mental/emotional/physical are all intertwined, representations of The Identity, or Infinite One.
