Human has 5 major senses:
Eyes, Ear, Tongue, Nose and sexual one.

Apart from this, we may have:
Paining, sense of temperature, sense of pressure, different feelings etc...

Many times we become addictive to get pleasure through senses.
The intensity of addiction can become so high that we tend to feel
very uncomfortabe without "pleasure".

Senses are ours, we are not of senses, but in state of extreme addiction,
we become slaves of sense stimulations.

When a person smokes one ciggarette, it gives him pleasure for hardly
5 minutes, after that desire of pleasure doesn't end but it increases
and this time with greater intensity.

People argue that, why God has created such things to cheat
with their mind itself. God has also created spikes in trees of
fruits and flowers, why don't they eat spikes then. People are
willing to throw the blame on others instead of admitting a terrible
mistake.

This addiction gradually leads to greater and greater desire for sense
pleasures. Senses enjoys that person but person thinks that
he is enjoying senses.

"People asks that they couldn't find God anywhere. But they
don't understand that they have filled their mind and heart
with oveflowing desires of sense pleasures."

To put somehing in a container, it must be empty, same is the case with
sensual pleasures.
