Life,the art that needs our hearts

When must we be cautious, when let go?
Who knows how to choose the better  part
When to use our will and when to flow
When to plant  the seed and watch it grow
When  ought we be cautious, when let go?
When to bend  as wilder winds can blow
How to live,the art that needs our hearts
When  may we be cautious, when let go?
Who knows how to guess the better  part?
