Sixth Sense

The sixth sense as described by the lexicon interpretation, is a power of perception autonomous of the five senses viz., sharp intuition. Others term it ESP or Extra Sensory Perception. So the question that one would like to reply is: How to activate the sixth sense? The reason is that the meaning is, as it were, lost for a majority of people. It's like the eyes closed and unable to see, can't be used for as long as they're shut.
