Limits

There are speed limits for driving on streets, roads, and highways.
There are limits set for deposits and withdrawals in banks and ATMs.
There is a limited time set for each class in schools and colleges.
Even in examinations, there is a time limit for giving proper answers.

But there is no limit set for thinking and developing ideas.
The scope and spectrum of thinking are unlimited.
Whether the thoughts are good or bad - 

whether the thoughts are pure and sacred or impure - 

whether the feelings are for the benefit of others - to do good to all or to harm - to cause pain to them - 

there is no limit set for all these thoughts and emotions.

We can fly in the open sky through our thoughts - as high as possible - or fall to the underworld.
There are no restrictions or limits on thoughts and emotions set by nature. 

It depends on us in which direction we want to proceed - whether to grow further - rise above our current level, or fall below.
If we wish to rise above our present level, then we must try to improve our thoughts towards betterment.
Thinking good - speaking good - and doing good will bring us good in return.
