Someone once told me that the simplest way of meditation is "just think of Swami in a relaxed manner...". I too thought this was the best way. I was glad to hear a similar opinion from another Sai devotee. This is because I'm not a yogi/jnani to adhere to strict meditation rules and restrictions. So, I just follow my heart. But, let us here take a look at the real aspects of meditation and to find out 'why meditation?'. We have Bhagavan Himself to explain to us on this matter :

     "It is not practical to attempt to concentrate on that which has no form. The object of concentration can be sound, form etc. It needs to be something concrete. It is not easy to fix the mind on the abstract.....
     The light is first moved into the heart which is conceived as lotus, the petals of which will open. The 'jyothi' is then moved to the other body parts. There is no particular sequence. But important is the final body station, which is the head. There the light becomes a crown enshrining and covering the head. The light is then moved outside, from the particular to the universal. Move the light into relatives, friends, enemies, trees, animals, birds until the entire world and all its forms are seen to have the same light at the centre and has been found to be within oneself.
     The idea of moving the light into the universal phase, the idea of universality is that the same divine light is present in everyone and everywhere... One should understand that what comes about in meditation as one moves deeply into it, is not the thinking of the light, but the forgetting that the body is not oneself. This is the stage of Contemplation when the body is totally forgotten. It cannot be forced.
     There are 3 stages: Concentration, Contemplation and Meditation. If the meditator remains conscious of himself and that he is engaged in meditation, the he is... still in the preliminary stage, at the beginning of concentration. ...Spreading the light into its universal phase, sending the light into every other body, and when 
one is so concentrated in that he is no longer conscious of his body, is the stage of contemplation... When contemplation deepens, it moves naturally into meditation. ...In the state of meditation, the meditator, the object of his meditation and the process of meditation have fallen away, and there is only one, and that One is God. ...All that may change has fallen away and 'Tat Twam Asi' - That Thou Art, is the state that exists. As one gradually returns to his customary and habitual state of consciousness, the 'jyothi' is again placed in the heart and kept lighted there throughout the day. 
     Meditation is entirely above the senses... Concentration is below the senses. Contemplation which lies in between, is partially within the senses and partially above the senses."

Swami says that the object chosen for concentration is just a "device to allow one to sink deeply into quietness and to allow the body, which is non-self, to fall away, out of consciousness".

     "Why a light?...From the water tank, if each one takes, the tank will go dry. But a thousand people can take the flame of one candle to light their candles and the flame is in no way diminished. ...Meditation on light is real meditation. Light is formless, eternal and divine. It is the safe way and sure way. But, Love is the royal highway to God. God is Love. God is reached only through Love."
