On attaining this realization, one ceases to differentiate between self and others. As a result, selfishness, unwholesome behavior such as stealing and killing for personal gains, hatred towards enemy and greed towards objects of desire will cease as well. From the perspective of Theravada, once these defilements are purified, one is deemed to have found the way out of samsara and attained liberation for oneself, which is the ultimate goal of Theravada practitioners. It means no more suffering and rebirth. Whereas in the minds of the bodhisattvas, purification of defilement is only the start toward their goal of being better equipped to benefit others. As realization of emptiness has destroyed selfishness, they can, from that point on, dedicate themselves entirely and unconditionally to benefit others. Therefore, one should endeavor to realize emptiness for one’s own sake and others’ as well. If not, the root of all delusions will still remain even though the more obvious defilements are reduced by other practices.
