Kadamba Kanana Maharaj
It is not easy to give up blaspheming devotees through determination only, thinking that just determination can work is illusion, its trap of maya. You fail, You hide and live in shame because Maya is more powerful than your determination.
Jayapataka Swami
When we expose ourselves to severe vaisnava-aparadha, it is like pulling our devotional creeper out from the root. It doesn't get the nourishment then we systematically dry out, then we lose the taste for chanting, reading, deity worship, book distribution, what could be worse! We lose devotional service ultimately.
Mahanidhi Swami
Vaisnava aparadha includes actions of the body, mind, words and heart.
Mahanidhi Swami
The main cause of Vaisnava aparadha is association of materialistic people which makes one feel envious of devotees, judge them by material standards and find faults with them.
Subhag Swami
Many people do devotional service but commit offenses to other devotees. Then bhakti gets reduced.”
Bhakti Charu Swami
The biggest hindrance to our spiritual progress is Vaishnava Aparadh.
