Buddha's Words...

A man asked Lord Buddha
"I want happiness."
Lord Buddha said first
remove "I" that's ego.
Then remove "want"
that's desire. See now
you are only left with
"Happiness".

Diligence in action...

Do not wait another second to practice. Do something about it immediately.
Totally abandon worldly activities and devote yourself to the practice of the Dharma right now. Otherwise you will never find the time -- one worldly activity will follow another , endlessly like ripples on the water. They will only stop when you decide once and for all to put an end to them.

As the omniscient Lonchenpa says:
Worldly preoccupations never end until the moment we die
But they end when we drop them -- such is their nature.
Patrul Rinpoche.

10 Virtuous Activities

There are ten virtuous activities that you should engage in to produce the cause for buddhahood.

The second is offering to the three jewels;
The third is generosity;
The fourth is attentiveness to dharma discourse;
The fifth, recitation of dharma, for example, reading the kangyur;
The sixth is memorization;
The seventh is teaching others;
The eighth , reciting prayers;
The ninth, contemplation upon the meaning;
and the Tenth, meditation upon the meaning.

Karma

As a Buddhist, someone who believes in the law of cause and result, you should know that every time you feel discontent, every time you suffer, it is only because you have accumulated non virtue in the past. You have accumulated the cause and your suffering is the condition and result of what you yourself have done. There is no such thing as a fruit( or result) without a seed; nothing happens without a cause.
