Caitanya Mahāprabhu said that, "Anyone who will take this message of Kṛṣṇa consciousness will be happy, and they will feel obliged to Me." That is stated in Caitanya-caritāmṛta, that "When people will take this message of Kṛṣṇa consciousness all over the world, in every city and every town, they will feel obliged to Me." Kṛṣṇa Caitanya Mahāprabhu said like this. You have read in Caitanya-caritāmṛta.
So actually the world is feeling so much disturbed by the arrangement of—misarrangement, not arrangement—misarrangement of the leaders of the society. They have forgotten Kṛṣṇa, or God. They are thinking that by material advancement they will be happy. But that is never possible. Just try to spread this message of Kṛṣṇa consciousness. It is very easy and very fact. Everyone can accept.
So on this occasion, when you have come here from San Francisco prepared to go to London, so my hearty welcome to you, and please do this missionary work very nicely and Kṛṣṇa will be pleased upon you. It is said in the Bhagavad-gītā, na ca tasmān manuṣyeṣu kaścin me priya-kṛttamaḥ (BG 18.69). Anyone who is trying to spread this Kṛṣṇa consciousness movement is the most dear friend of Kṛṣṇa. If you want to please Kṛṣṇa, Kṛṣṇa says that "Anyone who is trying to spread this Kṛṣṇa consciousness movement, he is My most dear friend."
Na ca tasmān manuṣyeṣu kaścin me priya-kṛttamaḥ (BG 18.69): "Nobody is so dear to Me as such person who is trying to spread Kṛṣṇa consciousness movement in the world." So you are all pledged to satisfy Kṛṣṇa. So if you take up this work seriously, Kṛṣṇa will be very much pleased upon you.
