Translation

At first all the followers of Advaita Ācārya shared a single opinion. But later they followed two different opinions, as ordained by providence.

Purport

The words daivera kāraṇa indicate that by dint of providence, or by God’s will, the followers of Advaita Ācārya divided into two parties. Such disagreement among the disciples of one ācārya is also found among the members of the Gauḍīya Maṭha. In the beginning, during the presence of Oṁ Viṣṇupāda Paramahaṁsa Parivrājakācārya Aṣṭottara-śata Śrī Śrīmad Bhaktisiddhānta Sarasvatī Ṭhākura Prabhupāda, all the disciples worked in agreement; but just after his disappearance, they disagreed. One party strictly followed the instructions of Bhaktisiddhānta Sarasvatī Ṭhākura, but another group created their own concoction about executing his desires. Bhaktisiddhānta Sarasvatī Ṭhākura, at the time of his departure, requested all his disciples to form a governing body and conduct missionary activities cooperatively. He did not instruct a particular man to become the next ācārya. But just after his passing away, his leading secretaries made plans, without authority, to occupy the post of ācārya, and they split into two factions over who the next ācārya would be. Consequently, both factions were asāra, or useless, because they had no authority, having disobeyed the order of the spiritual master. Despite the spiritual master’s order to form a governing body and execute the missionary activities of the Gauḍīya Maṭha, the two unauthorized factions began litigation that is still going on after forty years with no decision.

Therefore, we do not belong to any faction. But because the two parties, busy dividing the material assets of the Gauḍīya Maṭha institution, stopped the preaching work, we took up the mission of Bhaktisiddhānta Sarasvatī Ṭhākura and Bhaktivinoda Ṭhākura to preach the cult of Caitanya Mahāprabhu all over the world, under the protection of all the predecessor ācāryas, and we find that our humble attempt has been successful. We followed the principles especially explained by Śrīla Viśvanātha Cakravartī Ṭhākura in his commentary on the Bhagavad-gītā verse beginning vyavasāyātmikā buddhir ekeha kuru-nandana. According to this instruction of Viśvanātha Cakravartī Ṭhākura, it is the duty of a disciple to follow strictly the orders of his spiritual master. The secret of success in advancement in spiritual life is the firm faith of the disciple in the orders of his spiritual master. The Vedas confirm this:

yasya deve parā bhaktir yathā deve tathā gurau
tasyaite kathitā hy arthāḥ prakāśante mahātmanaḥ

“To one who has staunch faith in the words of the spiritual master and the words of the Supreme Personality of Godhead, the secret of success in Vedic knowledge is revealed.” The Kṛṣṇa consciousness movement is being propagated according to this principle, and therefore our preaching work is going on successfully, in spite of the many impediments offered by antagonistic demons, because we are getting positive help from our previous ācāryas. One must judge every action by its result. The members of the self-appointed ācārya’s party who occupied the property of the Gauḍīya Maṭha are satisfied, but they could make no progress in preaching. Therefore by the result of their actions one should know that they are asāra, or useless, whereas the success of the ISKCON party, the International Society for Krishna Consciousness, which strictly follows guru and Gaurāṅga, is increasing daily all over the world. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura wanted to print as many books as possible and distribute them all over the world. We have tried our best in this connection, and we are getting results beyond our expectations.
