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 TolleTrue freedom and the end of suffering is living in such a way as if you had completely chosen whatever you feel or experience at this moment. This inner alignment with Now is the end of suffering. Is suffering really necessary? Yes and no. If you had not suffered as you have, there would be no depth to you as a human being, no humility, no compassion. You would not be reading this now. Suffering cracks open the shell of ego, and then comes a point when it has served its purpose. Suffering is necessary until you realize it is unnecessary.
Eckhart TolleWhen you are fully present with everyone you meet, you relinquish the conceptual identity you made for them - your interpretation of who they are and what they did in the past - and are able to interact without the egoic movements of desire and fear. Attention, which is alert stillness, is the key.
Eckhart TolleWhen faced with a radical crisis, when the old way of being in the world, of interacting with each other and with the realm of nature doesn't work anymore, when survival is threatened by seemingly insurmountable problems, an individual life-form -- or a species -- will either die or become extinct or rise above the limitations of its condition through an evolutionary leap.
