Srila Thakur Bhaktivinode
Śrī Caitanya-śīksāmrita 3.3
To be controlled by prejudice causes many problems. From prejudice arises partiality; from partiality comes disrespect for truth.
Wearing the signs of the vaisnava is one of the methods of cultivating devotion, involving the body. But to think that that is the distinguishing characteristic of a vaisnava is a prejudice arising from sectarianism. Con-trolled by such false beliefs, a person may not respect a real vaisnava who is not wearing those marks. If a devotee has such prejudice and he cannot find good association with in his own organization, he will not venture to find good association elsewhere. Since nothing can be accomplished without good association, such a devotee falls into a dangerous position. Those who are bound to the varnāśrama system by prejudice also fail to develop a taste for a higher level of bhakti. Sometimes hatred, which degrades a person even more, may also appear.
