The Buddha-Dhamma is a moral and philosophical system which expounds a unique path of enlightenment, and is not a subject to be studied from a mere academic standpoint.
The doctrine is certainly to be studied, more to be practised, and above all to be realized by oneself.
Mere learning is of no avail without actual practise. The learned man who does not practise the Dhamma, the Buddha says, is like a colourful flower without scent.
