Mind is our enemy. It is the agent of "Time" Its job is to puzzle and mislead the being. It entangles the being in the world and keeps it away from the wave of Divine sound (sound wave). We can't do any work good or bad without taking it along with in this land of "Time".
When the mind is made to follow the Divine sound (sound wave) it runs towards worldly attachment and perversions at once.
Thus it takes a lot of time to withdraw worldly thoughts, to concentrate attention at third eye or the centre between both physical eyes like:o^o and to manifest the radiant form of the "Lord". We have to fight severely with the mind in order to achieve this objective and we have to bear restlessness for a longer period. The progress in this practice is very slow. One needs to come with patience and firm determination daily in the ground/field of struggle.
Withdrawing attention from the body and concentrating at the Third eye is like an ascending with the speed of an ant. The ant ascends on the wall, falls down and tries again to ascend and falls again. Similarly, we try to take the attention within and the mind wanders outside. We succeed sometimes whereas mind succeeds sometimes. It is a lifelong struggle.
As the scattered attention starts concentrating then the wandering of the mind decreases and one starts feeling peace and Nectar within. The hands and feet start sleeping and slowly and steadily the legs and the top part start sleeping. These are the marks of progress in repetition. We should have a close watch at our condition within in this practice and we should try to step ahead. The path is lengthy and the traveller, whose journey is long ,always keeps his eyes on the way and keeps on stepping ahead continuously.
