In the materialistic world, people are pleasure hunters, they think happiness and peace comes from money. So everyone is in the path of money making whether in right way or wrong way, money has become there ultimate goal. They wish only for permanent happiness and think money can buy happiness and peace. Riches, success and achievements may bring name, fame and pride, but they do not always bring permanent happiness.
If lack of money and success creates misery and suffering, their possession does not give happiness either. The question then is how one can be peaceful and happy, irrespective of whether he is a success or failure in his life
First, one has to know what self is. If one knows self is not physical but self is consciousness, he knows the physical existence is mere mirage created out of consciousness.
God/ Christ /Brahman/Buddha's nature/Atman/Soul/Self are one and the same thing called with the different name for the ultimate truth. The ultimate truth is consciousness. One has to recognize it, without the form and name and become one with it.
To the one without peace, how can there be happiness unless a person is tuned his focus of attention to soul/self, he cannot have peace and without peace, he cannot be happy. A person without the self-knowledge, experiences the birth, life, death or universe as reality.
So if one wants non-dual peace, he has to acquire Self-knowledge. For this, he need not have to abandon the pursuit of riches, success and achievements but he must have intense urge to know the ultimate truth. Knowledge of consciousness means Self-Knowledge or Brahma Gnana or Atma Gnana. The consciousness pervades in everything and everywhere in all the three states, therefore one has to realize sameness towards all the three states, because everything is created out of the consciousness.
A waking or dream centric person remains alienated from wisdom that is consciousness. If one is free from reasoning on the base of waking entity, he looks at all the three states as consciousness and so is united to the wisdom that is consciousness. He will be free from experiencing duality/illusion as reality, and will attain the non-dual peace, which is the nature of the consciousness.
