Let me start off with knowledge acquired on day 1:
- A prayer that I have learnt to chant as a kid but I never fully understood
"asato ma sadgamaya
tamaso ma jyotirgamaya
mrtyorma amrtam gamaya"
Means
Lead me from unreal to the real (or untrue to truth)
Lead me from darkness to light
Lead me from death to immortality
How beautiful!! - "Prana" is sanskrit for "breath". (I always thought Prana literally meant life)
Also came across an interesting parable on this matter. According to the upanishads, the 5 senses were having a discussion about which is the most important. They decide the only way to find out would be if they leave one by one and the others experience life without one sense. First, sight goes off for 1 year and once it is back, it asks the others, "how was life without light?". The other senses say, "the world was plunged in darkness. Life was bad but we got used to it and we began to rely on touch, sound etc to fill the void left. Life went on.". Similarly, hearing, touch, taste go out one by one and realize that life continues in their absence. Finally, it is breath's turn to leave. As it starts making its exit, the other senses realize that they too were disappearing along with breath. They realize their folly and accept that breath is the most important of the 5 senses. This is why prana, the word for breath, is often used to denote life. Infact, "prani" is the word used for "creatures". Interesting.
