The object of meditation is to transfer the centre of attention to inner and more real things, compared to which the outward shows are like shadows. The door to those inner realms is above and behind the two eyes, and it is by persistently knocking at those gates (concentrating the attention between the two eyebrows) in the manner taught to you at the time of initiation, that admittance is gained.
The easiest way to achieve this, without disturbing normal existence and upsetting existing relations, is to practise meditation for at least two and a half hours every day so that one learns to withdraw the attention gradually and voluntarily and also to hold it there. This preliminary work is hard, and in the beginning it is tiring and boring also, for the tendency of the human mind is to go out, and not in. It is only by going in that we can reach the kingdom of God. Once concentration has been achieved, the rest becomes comparatively easy, for then bhajan is delightful. However, for the average individual, this is almost the work of a lifetime. But when this has been accomplished, one literally rises above the world.
The eye centre is the door that leads up into higher regions, and down into this body or the world as well. The world exists for us and influences us only when we play through the nine doors, but when we make for the tenth door we rise above the world. It is then that we acquire strong faith in the Master and realize that in whatever we have to face, to go through, the Master is always with us and guides and protects us.
