The modern scientific age began when Nicholas Copernicus proposed that the earth revolves around the sun. His ideas were later improvised by scientists like Kepler, Galileo, and notably by Isaac Newton, who discovered laws that governed the motion of the physical bodies and the law of gravitation. Further, James Clerk Maxwell showed that magnetism and electricity too could be deduced by a set of equations. The philosophical implication of these scientific developments is that the whole universe is determined by physical laws. This is called the principle of determinism. This law was prevalent in scientific circles up to the end of the 19th Century.
In spiritual life, all our attempts are directed towards the realisation of God and all our spiritual pursuits are centred around remembrance of God. An ordinary mind moves in different directions and so, is disturbed. The concentrated mind is one-pointed but its object may be a worldly one. Such a concentration will not help us spiritually. And so, the mind should be concentrated on God. It is an enormous task. However, we can practice it remembering God more often.
