Sidharth, while living in his luxurious palace, eagerly wanted to go out and see the outside world… where he saw an old man, a dead body being carried by four men, a sick person and a sage…

opening his two eyes to the very truth of this earthly reality made him realize the two very important undeniable earthly principles…

one, everything dies on earth…which means everything is temporary…
two, nobody can own any richness…which means through any riches too, nobody can gain permanent pleasure and can not safeguard from the first law of impermanence…

thereafter, he searched for truth…not by closing his eyes to the very truths of this world…

open two physical eyes to the physical world (आधिभौतिक) first, then, the spiritual eye be opened to the spiritual world (आध्यात्मिक)…path is through body (दैहिक) to divine (दैविक)…that’s why bow-D (body) is given on earth to solve the labyrinth of a bearth…
