Leonardo da Vinci: the more you know about him, the less you know about him

Leonardo's wisdom was built on adherence to sound principles. His dedications were not focused inward, not dedicated to arrogance and self seeking.
He wanted answers.

So as to be able to give something of worth to his fellow humans after his passing. This can be said for Newton, Einstein, Socrates also. Their aims were altruistic, a quality of which must great human possess. Having attained such a level of detachment from the more corrupt side of self, many wonderful human attributes come forth.

One of these attributes is called generosity. What better way to spend life than to generously share our accomplishments and achievements with others?
This condition is called 'servitude'.
To share generously with fellow human being could be achieved indeed. Whatever material benefit accrued from this condition of generosity is simply the manifestation of natural law:
one who gives will receive.

When the rains pour the seeds sprout. The sun ceaselessly gives generously of itself and the result in life.
Should the sun decide to be selfish, exist alone and for lorn in the universe? Its very existence is made meaningful by the degree and quality of its generosity.

The greatness of any person then is due to the degree by which the attribute or generosity manifests itself. An apple tree brings forth fruit and out of generosity humans and animals alike thrive.
A fruitless tree is fit for the fire.
A wise painter is he who having achieved a high level of maturity in his art is socially generous with his accomplishments. He has the choice during his own lifetime or past humously.

Success is a very slow and pain taking pocess, often taking almost a lifetime to accomplish. Its seeds are sown in the soil of hard work and dedication without much thought to reward.
To work without thought of reward is a condition of love.
