They dont clear past knowledge, it is there for you to find if youd like 
Memories from past lives can be remembered through meditation etc., just like memories from your early childhood can be remembered.
You say "They clear past knowledge" like someone else does it to you. You make a concsious decision IMO.
As for only seeing the bright side, there are 2 sides to everything. Pain and pleasure only control you if you let them, again IMO. There is no "system" of pleasure and pain, you bring these things upon yourself.
Thats not a very good metaphor. I guess a more accurate metaphor would be, you go through kindergarden, graduate, and decide wether or not you want to move on to 1st grade. Once you start 1st grade you can of course remember all the past teachings,(this knowledge we call intuition) but you forget things like conversations you might have had with classmates, the grade you recieved in K, etc. etc. But using a school as a metaphor isnt very reliable in itself

QuoteWell, I thought about it, but I dont see it. Just think about your school, what would be your condition if you forget completely the things you learnt in the past standard, as soon as you enter the next standard ?
