Re-reading it, I can see that as he said, it's hard in life while living a life to completely close yourself off. And because of this, we who come into the life (as a soul), will take on certain vibrations just by those we associate with (loves, enemies, friendships, ) as we live it.
At the end of the road, now, it's more about the assessment of being (as I call it) a vegetable in a pot of soup......just by being a part of the world, you can't help but take on a certain flavour of it, even though you try your best not to at times.
