This was said by the Lord…
“Bhikkhus, one who has not directly known and fully understood hate, who has not detached his mind from it and abandoned it, is incapable of destroying suffering. But one who has directly known and fully understood hate, and who has detached his mind from it and abandoned it, is capable of destroying suffering.”
Humankind is possessed by hate,
Bound by hate and delighted with being;
Not fully understanding hate,
They come again to renewal of being.But those who have abandoned hate,
And who by destroying hate are freed,
Have conquered the bondage of hate
And overcome all suffering.
