The mind is a fantastic tool for our day to day operations. However, the mind and the different thoughts could become a blockage to our feelings and the enjoyment of life. We rely on thoughts, ideas and mental schemas even though life in itself chnages continually, making any reasoned prediction just another "educated" opinion. In the Spiritual realm thoughts, ideas, definitions and such could be a great obstacle to embrace life in its wholesomness.
A spiritual truth cannot be described in a concept or put as another idea. It is not intellectual talk or a way to solve logical riddles. A Spiritual truth is related with self knowledge in the understanding of our inter-relation with everything that exists, in the totality of life.
