Meditation Follows Concentration - Part 9

As a clever cook in serving his master notes the kind of food that his master relishes and
henceforward serves it and gets gain, so the aspirant too notes the conditions such as nourishment, etc., at the moment of attaining meditation and Samadhi and in fulfilling them gets ecstasy again and again. Leading a virtuous life is not by itself sufficient for God-realisation. Concentration of mind is absolutely necessary. A good virtuous life only prepares the mind as a fit instrument for
concentration and meditation. It is concentration and meditation that eventually lead to
Sell-realisation or God-realisation. “A Yogi should always avoid fear, anger, laziness, too much sleep or waking and too much food and fasting. If the above rule he well and strictly practiced each day, spiritual wisdom will arise of itself in three months without doubt. In four months, he sees the Devatas; in five months, he knows (or becomes) Brahmanishtha; and in six months, he attains Kaivalya at will. There is no doubt.” Amritananda-Upanishad. During meditation some of the visions that you see are your own materialised thoughts while some others are real objective visions. In meditation new grooves are formed in the brain and the mind moves upwards in the new spiritual grooves. In meditation and concentration you will have to train the mind in a variety of ways. Then only the gross mind will become subtle.When you first practice meditation, lights of various colours such as red, white, blue, green and a mixture of red and green, etc., will appear in the forehead. These are Tanmatric (elemental) lights. Every element has got its own colour. Water has white colour. Fire has red colour. Air has green colour. Ether has blue colour. So the colourful lights are due to these Tattvas (elements) only Some times you may see a big blazing sun or moon or lightning in front of the forehead. Do not mind these. Shun them. Try to dive deep into the source of these lights.
