“… looking for meaning on the level of mental concepts and if you look for meanings on the level of mental concepts all you can find is transitional temporary things. Belief Structures. Belief systems that can be satisfying for a while but sooner or later your belief system will clash with reality and will lead to suffering. So to look for the true meaning of life cannot be found. If you are able to relinquish your desire to understand conceptually and access that in you which is beyond concepts then you find the meaning of life but you may not be able to say what it is.” – Source: Eckhart Tolle
