There is no sight comparable to knowledge.
Knowledge enables one to see beyond what is visualized.
There is no discipline comparable to Truth.
It takes tremendous discipline to speak what is truth under all circumstances.
(This cannot be described more beautifully than by Bhagwan Krishna in Ch2: dhyayato visayan pumsah sangas tesupajayate sangat sanjayate kamah kamat krodho 'bhijayate krodhad bhavati sammohah sammohat smrti-vibhramah smrti-bhramsad buddhi-naso buddhi-nasat pranasyatiWhile contemplating the objects of the senses, a person develops attachment for them, and from such attachment lust develops, and from lust anger arises.From anger, delusion arises, and from delusion bewilderment of memory. When memory is bewildered, intelligence is lost, and when intelligence is lost, one's destruction is total.)
There is no happiness comparable to renunciation.
(In the words of the the Kaivalya Up Na karmana na prajaya dhanena tyage naike amrtatva manushu - Neither by works nor by progeny nor by accumulating wealth but only through renunciation is there any attainment of beatitude)
