जले तैलं खले गुह्यं

जले तैलं खले गुह्यं पात्रे दानं मनागपि।

प्राज्ञे शास्त्रं स्वयं याति विस्तारे वस्तुशक्तितः॥

cāṇakyād

Another sweet gem from Chanakya

Oil added to water

Secret shared with an idiot or an evil minded fellow

Gift given to a deserving and nice person

Knowledge of science imparted to a man with great intellect

These spread and multiply all by themselves especially because of the qualities of the recipients..even if the quantity supplied is very small.

Oil and water do not mix with one another.. They have different specific gravities too..Obviously oil added to water floats over a vast area over the surface.

When we disclose a secret to an idiot or an indiscreet person, we know what happens.. The matter will be given a lot of make up too and presented everywhere ..

When a gift is given to a nice and deserving person, he will be grateful and we gain a good friend for ever.. The gift would be used for noble purposes..

And when we teach a nice, earnest and brilliant student, the knowledge and the benefits arising out of it grow and spread million-fold..

Of course no special mention is to be made of secrets shared with idiots..
