If this doctrine is not understood thoroughly, 
The conception of an I prevails,
Hence come virtuous and non-virtuous actions
Which give rise to good and bad rebirths.
Therefore, as long as the doctrine of removing
The conception of I is not known
Take heed of the practices
Of giving, ethics, and patience.

Nagarjuna (150-250), Nāgārjuna is widely considered one of the most important Buddhist philosophers.
