Surrender is to give oneself up to the original cause of one's being.

A realized one sends out waves of spiritual influence in his aura, which draw many people towards him. Yet he may sit in a cave and maintain complete silence.

An unawakened person sees only his mind, which is merely a reflection of the light of pure consciousness arising from the Heart.

The activity affected by causes like fainting, sleep, excessive joy, grief, possession by spirits, fear etc goes to the heart, its own place.

Without seeing the origin of light, the true form of one's Self, the ordinary man sees by the mind different things and is deluded.

...the Lord of the Universe carries the entire burden of this world. You imagine you do. You can hand all your burdens over to His care. Whatever you have to do, you will be made an instrument for doing it at the right time. Do not think you cannot do it unless you have the desire to do it. Desire does not give you the strength for doing. The entire strength is the Lord's.

It is false to speak of realization. What is there to realize? The real is as it is always. We are not creating anything new or achieving something which we did not have before. The illustration given in books is this. We dig a well and create a huge pit. The space in the pit or well has not been created by us. We have just removed the earth which was filling the space there. The space was there then and is also there now. Similarly we have simply to throw out all the age-long sanskaras [innate tendencies] which are inside us. When all of them have been given up, the Self will shine alone.
