“We might be engaged in devotional activities, but due to some improper activities such as offences to devotees (vaisnava aparadha), to the spiritual teachers (guru-aparadha), to the holy places (dhama-aparadha), while chanting the holy name of God (nama-aparadha), or during service (seva-aparadha), we might suffer from imbalances and stagnations that can cause intense suffering.” – Srila Bhakti Tirtha Swami.
