Prabhupāda said, “Mumbai is the most advanced city in India, so we need to give them Kṛṣṇa Consciousness and this will positively affect all the rest of India.” So, Prabhupāda had a great vision about Mumbai and preaching in India. He wanted to see that the ancient culture of India should be preserved and that be adapted to the modern situation. He had successfully preached all over the world and he was ordered by Deities in Los Angeles to also preach in India. So, he established his centre here in Mumbai…
So, Prabhupāda, he walked on the Juhu beach, he would naturally give his vision, how people could be properly situated. So, we are very grateful that Prabhupāda, he declared Mumbai as his office and that’s a great responsibility for all of you because Prabhupāda wanted that from Mumbai, he would spread Kṛṣṇa Consciousness all over India. He thought my foreign devotees have to visit Vṛndāvana and Māyāpur; but Mumbai was a special project. It was meant to deliver the Indians.
