Can esoteric knowledge be found in various fields, including spirituality, mysticism, alchemy, and the occult?

Without a doubt, Esoteric knowledge can become available to those who practice the spiritual side of thinking and maintain an open mind while doing so. In general, one needs an open mind to practice as it is, but do not take everything that is learned at face value, for not all things are what they seem, yet everything can be a learning experience if you stay vigilant.
