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.
One doesn't stay in a state of nirvana by hiding from difficulties. You stay in nirvana by lavishing nirvana on everyone you meet, by giving it away as fast as you receive it.
If you think that people should be nice to one another, then by
all means be nice. But when you project that belief onto the
people and the world around you as if it were an objective reality,
or worse still, as if it were their job to be nice to you, you put
yourself at odds with what is, and suffering will surely follow.
