If the only teacher you have is your suffering, you will need a substantial dose of it for the ego to dissolve. But if the power of spiritual teaching is already at work, then a minor event can dissolve the ego.
Eckhart TolleIf you have a strong ego [and] something good happens to an acquaintance of yours, [it] makes you feel bad. It's called envy. ... The ego thinks something has been taken away from you because somebody else has received something good. It's a complete illusion, but that's the madness of the ego.
Eckhart TolleWhen life takes away the forms that you thought were the foundation of your life, what's left? The life that needs no foundation - that is the foundation. The formless. The essence.
Eckhart TolleIf you keep your attention in the body as much as possible, you will be anchored in the Now. You won't lose yourself in the external world, and you won't lose yourself in your mind. Thoughts and emotions, fears and desires may still be there to some extent, but they won't take you over.
Eckhart Tolle
