First, meditation should be of a negative nature. Think away everything. Analyse everything that comes in the mind by the sheer action of the will. Next, assert what we really are-existence, knowledge, and bliss-being, knowing, and loving.
If a person who lives in God becomes miserable, what is the use of living in God? What is the use of such a God? Throw such a God overboard into the Pacific Ocean. We do not want such a God!
Man stands in materialism; you and I are materialists. Our talking about God and Spirit is good; but it is simply the vogue in our society to talk thus: we have learnt it parrot-like and repeat it. So we have to take ourselves where we are as materialists, and must take the help of matter and go on slowly until we become real spiritualists, and feel ourselves spirits, understand the spirit, and find that this world which we call the infinite is but a gross external form of that world which is behind.
You have the right to work, but do not become so degenerate as to look for results. Work incessantly, but see something behind the work. Even good deeds can find a man in great bondage. Therefore be not bound by good deeds or by desires for name and fame.
Life is called Samsara - it is the result of the conflicting forces acting upon us. Materialism says, "The voice of freedom is a delusion." Idealism says, "The voice that tells of bondage is but a dream." Vedanta says, "We are free and not free at the same time." That means that we are never free on the earthly plane, but ever free on the spiritual side. The Self is beyond both freedom and bondage. We are Brahman, we are immortal knowledge beyond the senses, we are Bliss Absolute.
It is weakness, says the Vedanta, which is the cause of all misery in this world. Weakness is the one cause of suffering. We become miserable because we are weak. We lie, steal, kill and commit other crimes, because we are weak. We die because we are weak. Where there is nothing to weaken us, there is no death nor sorrow. We are miserable through delusion. Give up the delusion and the whole thing vanishes.
We should cultivate the optimistic temperament, and endeavour to see the good that dwells in everything. If we sit down and lament over the imperfection of our bodies and our minds, we profit nothing; it is the heroic endeavour to subdue adverse circumstances that carries our spirit upward.
The mind in its foolishness thinks that it is working in this body. Why should I be bound by one system of nerves, and put the Ego only in one body, if the mind is omnipresent? There is no reason why I should.[Source]
The root of that degeneration is egotism - to think that one is just as great as any other, indeed!
