fundamental lies

Why do we lie to ourselves and hence lie to the people we love ie all the people we interact with a parent to children a teacher to student, is it because we don't understand thought and it's limits?  why do we live in conflict and confusion?

I have looked at many religions, political beliefs and no one can explain them are they inventions of the mind like countries? are these the biggest lies we tell ourselves

We will be looking at how we can understand ourselves on an individual basis as this is the only way- as nobody can lie to us and we can not lie to ourselves. The best people I have found are Jiddu Krishnamurti on understanding yourself [He also failed in explaining his thinking ] and on looking at universal power Jean Houston [ Which seems to be LOVE as is claimed by Albert Einstien and current Physics thinking.]
