(Kadamba Kanana Swami, 16 April 2014, Durban, South Africa, Srimad Bhagavatam 1.7.34)
The first and foremost quality of the brahminical order is kṣamā or forgiveness. This is the beginning of tolerance. See, external tolerance will not do. One can act very tolerant but if internally one cannot forgive then internally one is burning with fire and burning with anger. So forgiveness is the foundation of tolerance, like the tolerance of a brahmana.
