Jai Sri Ganesha,
Imagination overshadow the truth of reality is truth of time and ages, many a times rope is taken as snake or vice versa, is nothing over power of imagination,
Illusionary trembling caused by hidden fear that intact in mind may cause rise to illusion,
Illusion is nothing but ignorance that can be destroyed by the dawn of true knowledge, and the giver is Lord Shiva,
Knower of Shiva though appears as if dies at the changeover but it is not a death but a liberation from the jaws of Morality,
