The Dhammapada - 19 & 20

Verse 19:

Though he recites much the Sacred Texts , but is negligent and does not practise according to the Dhamma, like a cowherd who counts the cattle of others, he has no share in the benefits of the life of a bhikkhu .

Verse 20:

Though he recites only a little of the Sacred Texts , but practises according to the Dhamma, eradicating passion, ill will and ignorance, clearly comprehending the Dhamma, with his mind freed from moral defilements and no longer clinging to thisworld or to the next, he shares the benefits of the life of a bhikkhu .

The scholar who knows a great deal but does not practise in accordance with the Dhamma is like a cowherd, who looks after the cows for wages, while the one who practises in accordance with the Dhamrna is like the owner who enjoys the five kinds of produce of the cows*. Thus, the scholar enjoys only the services rendered to him by his pupils but not the benefits of Bhikkhu. The other bhikkhu, though he knows little and recites only a little of the sacred texts, having clearly comprehended the essence of the Dhamma and having practised diligently and strenuously, is an 'anudhammacari'**, who has eradicated passion, ill will and ignorance. His mind being totally freed from moral delilements and from all attachments to this world as well as to the next, he truly shares the benefits of Bhikku.

** Anudhammacari: one who practises in conformity with the Dhamma.
