Forced experiences wean us away from the world

1  Many times objects force themselves on to our awareness
    forcing upon us pleasure or pain of an unknown degree
    The memory of these experiences themselves is 'active memory'

2  We also realize our 3-fold helplessness from these experiences
    a)   We have to experience these objects forcing themselves upon us
    b)   We do not know when these objects will force themselves upon us
    c)   We have to experience both pleasure and pain springing
           from the contact with these objects
    The memory of this 3-fold helplessness is 'passive memory'

3   A combined working of these 2 memories gradually forces our minds to be so alert
     as to constantly wean us away even from our habit of experiencing
     objects of pleasurable experience
