Guru and prana

There was sudden early morning thought today about the similarities between guru and prana. First and foremost is that both are idespensible needs for our survival. The second similarity is the guru and prana are embodiments of equality. Every living thing utilises prana for its survival. Prana offers itself to one and all, it has no differences between good, bad, rich, poor, male, female, nationality or religion or even a Saint and sinner. Same way Guru has no priorities or restrictions among living things. He just offers himself for one and all, it is only the people who assume differences and consider oneself as more important but guru himself is eternally unbiased in his nature.
