LEARNING OF UNDERSTANDIG

This whole creation exists in contradiction and duality. one has become two and at the same time twos are the one . many a twos in this world of appearance ,seem to be two but behind the curtain they are one. see ,day and night are two but all the 24 hours that include day and night named "DAY". without night day can not exist and without day night can not exist . but both seem to contradictory to each other. this is the one simple example and whole universe living and nonliving; laws and lawlessness ;life and death ; joy and misery ;profit and loss ; darkness and light ;knowledge and ignorance ; all are at the same time two as appear but one when exist ;contradictory and contrary but the same time also complimentary and unexceptionably necessary for the existence of the other.
this kind of understanding ,when developed that is to feel and understand the two in one or the one in two is the perfect and pure understanding . life and death (only one example taken applicable to all others ) are two opposite ends of the same rope of life. this is what is taught in all scriptures , all religions ,by all great thinkers and philosophers of the world in human history. that is why , i say ,one who knows his own religion knows the all. all the great men reached the same place may lead the different roads .
Lord Krishna told to understand the same thing ; to see the pain and pleasure in the same vein and called us to be STITHIPRYGYA i.e. keep oneself stable in pleasure and pain.that is the true and perfect knowledge and pure understanding of this universe.
" joy and woe are woven fine ; a clothing for the soul Divine = under every grief and pine ; runs a joy with silken twine = this is right ,this should be so ; man was made for joy and woe.= and when this we rightly know ; through the world we safely go " (the name of poet, not in mind)
and again ; please see , Then of the THEE in ME who works behind : The veil , i lifted up my hands to find : A lamp amid the darkness ;and i heard : As from without --THE ME WITHIN THEE BLIND ! "
