Even by growth and appearance of the trees so tall,
the fruits will never ripen unless the due season occurs;

Likewise, however we try repeatedly, whatsoever,
Unless the due time comes, whatever efforts you make,

taken up tasks will not become successful and fruitful!
Take up tasks in fitting time to achieve results beneficial!

Dr.V.K. Kanniappan
