The fast, festival and mythological legends are outcome of spiritual and philosophical doctrines. Their subtle, selflessness, spiritual mysteries are not much appreciated in the modern age, but we observe them as a matter of tradition. There is no dearth of scientific and physical base in them.
Science arrives at a conclusion only on the basis of a hypothesis.
Indian religious festival and legends expose the mystery of the real form of Truth by symbols, indications and by allegorical methods, which is most poignant and venerable. In modern materialistic world of reason and arguments, we pay no heed to it. To realize the sublime, spiritual and psychological truth in them, we need the persons of cooperative and element knowledge. When you understand them, the door to extreme happiness and welfare opens. With such devoted mind, the festival of Raksha Bandhan should be observed.
