I have been carrying around a little piece of paper in my wallet, with the words yare dekha, tare kaha on it. I finally went to Vaniquotes to see what these words implied.

yāre dekha, tāre kaha ‘kṛṣṇa’-upadeśa āmāra ājñāya guru hañā tāra’ ei deśa (Cc Madhya 7.128)

“Instruct everyone to follow the orders of Lord Śrī Kṛṣṇa as they are given in the Bhagavad-gītā and Śrīmad-Bhāgavatam. In this way become a spiritual master and try to liberate everyone in this land.”

…the sublime mission of the International Society for Krishna Consciousness. Many people come and inquire whether they have to give up family life to join the Society, but that is not our mission. One can remain comfortably in his residence. We simply request everyone to chant the mahā-mantra: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare.

…The real purpose of human life is to attain the spiritual platform and return to Godhead. That is the summum bonum of spiritual realization. The Kṛṣṇa consciousness movement is trying to elevate human society to the perfection of life by pursuing the method described by Śrī Caitanya Mahāprabhu in His advice to the brāhmaṇa Kūrma. That is, one should stay at home, chant the Hare Kṛṣṇa mantra and preach the instructions of Kṛṣṇa as they are given in the Bhagavad-gita and Srimad Bhagavatam. (from purport)

“Whomever you meet, simply talk with him about the instructions given by Kṛṣṇa or tell him of narrations about Kṛṣṇa.” (SB 4.23.38)
