The sixth sense/ intuition/ gut-feeling is an enigma as far as its genesis is concerned. But it is fantastic as far as its manifestation is concerned.
Is it due to establishing a connection with the Supreme Intelligence also called God?
Is it available to everyone?
Does it have a fixed operating frequency or does it have a broad, rather Infinite Bandwidth that is available to each one of the creation?
How can we tune in to the available frequency that is specially there for each one of us?
We must have our receptors ready and clean to produce the melody rather than keep transmitting jarring noise. Practice tuning in and be aware of changing frequencies.
