Read everything, listen to everybody, believe nothing, unless you can prove it with your own research - William Cooper
William Cooper is a controversial figure but I found his quote interesting and very much fits the spiritual paradigm of life. From a spiritual perspective, we must be diligent and serious in our studies of the scriptures. If necessary, study all World religious scriptures to get a broad perspective. In fact we should also study modern scientific literature seriously to understand how science is conducted. Then, we should listen submissively to leaders of the respective faiths and science. We should ask questions if necessary to clear our doubts in a cogent and comprehensive manner. Then only, finally, we should embark on the journey of life be it spiritual or material and discover life for ourselves. Otherwise, either religious, spiritual or scientific, if we do not follow the above steps, it is simply dogmatic to follow a particular way of life.
This quote is very much related to Bhagavad Gita and Krishna Consciousness. Unless, we deeply understand the inner meaning and essence of Bhagavad Gita, listen to the experts, how can we practice Bhagavad Gita in our own life and prove to our selves that Krishna exists? How can we gather evidence towards the existence of a Supreme Being? Therefore it is paramount to study, listen, and practice to prove to ourselves of a higher dimension. Blind following is not a sustainable and eco-friendly formula for a Bhagavad Gita way of life.
