The name of the book “Inner Engineering A (D.I.Y) User Manual “ is self explanatory. Divinity is proactively involved in blessing us and giving us what we need. However within our minds and bodies exist negative aspects because of which the blessings or benefits showered continuously upon us by Divinity don’t reach us. Our body is referred to as the temple of God. Our mind is the high priest who performs worship in this temple or is supposed to do so. Our stomach is the altar on which sacrifices are offered three to five times in a day. Our organs are the participants in this worship which is supposed to go on as long as we live. First and foremost we have to totally give up or bring to bare minimum our habits such as consuming alcohol. We have to give up totally drugs, tobacco and other sedatives. This is because the temple of the body has to be clean in order to perform an effective worship. The next important and a more important aspect is to shed our mind of all negative emotions like non forgiveness, non repentance, arrogance, anger, hatred, jealousy, greed and other negative emotions and thoughts. By clearing our mind we free immense energy within ourselves which can be utilized in productive activities. This leads to progress in life. Same way cleansing of the mind leads to mental and physical health. The books just gives a road map to healing our inner self or you may call it engineering our inner self with the aim to achieve fuller lives.
