Some different opinion:
"That which is produced by desire, anger and delusion is nonvirtue.
That which is produced by nonattachment, nonaggression and nondelusion is virtue." Nagarjuna
"If any teaching you study, reflect upon, or expound becomes an effective remedy against your disturbing emotions as well as an aid for allowing the pure Dharma to take birth in your being, then that is called a Mahayana teaching and is unmistaken." Guru Padma
