In order to be truly free, you must desire to know the truth more than you want to feel good. Because, if feeling good is your goal, then as soon as you feel better you will lose interest in what is true. This does not mean that feeling good or experiencing love and bliss is a bad thing. Given the choice, anyone would choose to feel bliss rather than sorrow. It simply means that if this desire to feel good is stronger than the yearning to see, know, and experience Truth, then this desire will always be distorting the perception of what is Real, while corrupting one's deepest integrity.
To get involved with a cause, you really have to become aware of it. You have to go on the ground and see with your own eyes, the people who have been affected by it, their process in how they're combating it, and what the organization represents.
