Now this is a very deep secret. It should not Have Queen written for the public. Yes Yogananda wrote it for his disciples
It tells why and how to meditate. There are deeper secrets – so anyone can accomplish it. This is how a yoga deals with life.
Here it is
Strong Will pulls energy from the Conscious Cosmic Rays surrounding the body through the door of the Medulla Oblongata. Man shall not live by bread (food chemicals) alone but by every word (vibratory life-energy) which flows (into the body of man) thru the mouth of God (i.e. the opening of the Medulla thru which the Conscious Cosmic Life Principle enters the body of man). Hence strengthen your Will and determination in everything. Your body shall be internally vibrating with life current. A man of strong Will, by his highly vibrating mind, can shake out disease, failure and ignorance. But the Will vibration must be stronger than the vibration of physical or inner disease. The more chronic the disease is, the stronger, steadier and more unflinching should be the determination, faith and effort of the Will to get well.Willingness and determination keep the blood vitalized with pep and life-energy. If even the layman can keep his mental initiative, willing-to-work attitude all the time, he will find his blood charged with life-current, making it immune against the invasion of bacteria.
