I think a certain level of level of awarenes, realisation and what I would call true intelligence and Knowledge, not knowledge as in accumulated memory, which in itself can be harmful, must be reached before any text,be it philosophical or religious, obviously not scientific, can be read without bias thus revealing the true meaning that was or was not intended for the knowledge known at the time.
Question, question and then question some more, your own motivation and that of others within the circle of influence of your friends family and loved ones but especially your children as they are the seeds of tomorrow. I especially would like everybody to question the intentions and effects of TV on children and even themselves and realise at the minimum-the huge effort made in trying to promote and glamourise, openly and subconsciously the sense of self and seperateness,with the 'I' and the ego been feuled to want bigger and better, or as one pop song of the early 90's put it-"I'm bigger and bolder,and rougher tougher" This was actually the verse of a song that was released when I was at school, the title was 'Dominator' but the the chorus is too much, "I wanna kiss myself." This is what is promoted from the start, so to actually realise that happiness lies in loss of the self-Is a feat in itself that numerically can only get smaller.
I've read before that the cross is the negation of the 'I'. This been literally the 'I' with a line through it. The cross been used religiously well before BC. I think the logicness of buddhism speaks for itself.
Truth is one, though the sages know it as many.
"What we are today comes from our thoughts of yesterday, and our present thoughts build our life to tomorrow:
Our life is the creation of our mind."
Dhammapada
Heaven is a state of mind.
Nirvana is a state of mind.
Both reached with the destruction of the self and all desires that tie us to this place.
Or as the Beatles said "All You Need Is Love".
