If a teaching diversifies by prescribing seemingly separate and unrelated causes to the diversities of life, then it is useless. Any true teaching should lead to a non-dual realization and direct the aspirant to the recognition that they already are what they are seeking and therefore the need to acquire anything is an illusion. While at the same time encouraging the aspirant to direct all one’s energy to discover the source of all known existence which becomes you.
You need only turn towards the Eternal, by turning away from the obstructions (namely, the desire to seek experiences through the senses and the fulfillment of thought as happiness which creates a seperate-self) that keeps one from coming in actual contact with the Source.
This does not mean forcing oneself to become aloof etc. Rather, allowing the actions of your particular life to go on outwardly, but inwardly you are not to concerned with outcomes as all your attention is primarily focused on: Who am I in spite of thought and body sensations? While feeling a deep reverence and love towards the Source, accompanied by an abiding desire to unite with that Source while remaining in a body.
