Where the mind needs new impulses and if there is no new experiences for the mind, then boredom sets in. People try different things:
free fall from a plane and see how long you can wait before you pull the parachute – ten meters above the ground …too late!
Like that in all kinds of countries people are taking to dangerous sports,
and try more excitement.
Some are trying intoxicants;
they try varieties of drugs and see what that does for you and expand your consciousness,
new horizons within, take a pill and experience ecstasy!
Of course it is artificial and plastic and imitation and again the same thing that feeling of emptiness is still not filled.
This is the nature of material life.
(Kadamba Kanana Swami 2005)
