『心偈』35

35「幸イトド　ムクイ　待タネバ」

How greatly happiness it is! 

If you don't wait for rewards.

'Itodo' means 'very'.

The most of our unhappiness has its roots in expectation of rewards.

All grudge, regret, struggle and agony are founded on selfishness.

Not waiting for reward is getting rid of oneself.

If you are ready for it, happiness is a definite promise.

Because everything turns a feeling of gratitude.

Any and all complaint is caused by selfishness.

Selfishness is waiting for reward. 

A mother has love to bring up children, so she doesn't hate hardships and sacrifices.

There isn't a promise more than love.

So pure love doesn't waiting for rewards.

Common acts, this is the best act.

Common is ”without me."  

Old days Budhidharma send a word"No act of charity" to Emperor Wu of Nothern Zhou, all act of men must be state of "No act of charity."  

Diamond Sutra demands charity to others "No act of charity."

Act is good for act of oneself.

It is the best act.  

It is act of ”without me."
