A.C. Bhaktivedanta Swami Prabhupada
While performing devotional service in the association of pure devotees in full Krishna Consciousness, there are certain things which are required to be vanquished altogether. The most important thing one has to surmount is weakness of the heart. All the problems of material existence are due to these weaknesses of the heart.
A.C. Bhaktivedanta Swami Prabhupada
One who is in knowledge of the Absolute Truth and free from all material desires becomes a pure devotee of the Lord.
A.C. Bhaktivedanta Swami Prabhupada
The root cause of devotional service to Lord Krishna is association with advanced devotees. Even when one's dormant love for Krishna awakens, association with devotees is still most essential.
A.C. Bhaktivedanta Swami Prabhupada
A devotee is considered superlative and superior according to his attachment and love.
