If you can clairvoyantly visualise the inner working of this mental factory you will see that, it is like a big telephone exchange, the messages come from diverse houses and firms into the central exchange. The operator plugs, connects and disconnects the various switches. So too, the mind plugs, connects and disconnects. When you want to see something the mind puts a plug into the other four senses (centres of hearing, smelling, taste and feeling). When you want to hear something, the mind plugs into the other four centres.
The mind functions at an unimaginable speed. There are numberless pigeon-holes in the sub-sconscious mind where various sorts of things are recorded in perfect order. There they are classified, grouped, labelled with accurate precision.
One impression rises up as a thought-wave and comes to the surface of the mind. It tickles the jiva (individual) into action. You can also see various colours in thoughts – spiritual or holy thoughts are tinged with beautiful yellow colour. If there is thought of anger, dark red arrows shoot out from the mind. There is perfect order in the cosmos – the working is smooth and harmonious because there is the antaryami ( inner controller) behind it, directing and guiding. In the mere presence of the inner ruler, the indwelling, interpenetrating presence, the mind and other inner faculties work without any friction.
There are different regions for sentiments, emotions, instincts, impulses. There are highlands and lowlands in the mind. There is the spiritual plane and there are the planes of the instinctive mind and the intellect. On the one side the will steps in to execute a certain strong desire of the mind. The other faculties, such as memory and the power of judgement and reflection stand behind, in a disciplined array, to help their master, the will. After the will has executed the order, imagination, come forward and speculates. Memory helps imagination.
Then the three gunas (qualities of nature), the various modes, and the thirteen evil vrttis (lust, anger, etc.), show their faces in different colours. They come to the scene, do their work and then retire for a rest. Words cannot describe how thrilling this scene is. Develop this clairvoyant astral sight through purification and concentration.
Do not forget the inner ruler who is awake even when the mental factory is closed down temporarily. Purify the mind. Practise concentration. Develop the power of the mind. Eventually you will merge with him.
