Śrīmad-Bhāgavatam is full of instructions by which one can become Kṛṣṇa conscious. Similarly, in the Bhagavad-gītā also, we receive the instruction how we can become Kṛṣṇa conscious. So Lord Caitanya selects these very two particular books, Śrīmad-Bhāgavatam and Bhagavad-gītā, and He asks everyone, in any part of the world, to take up this matter very seriously and preach in the world. That is the direct order of Kṛṣṇa.
So if we take up this missionary work, to preach Bhagavad-gītā as it is, without any interpretation and without any motive behind it, as it is, as Kṛṣṇa said... We should present as it is. People misrepresent Bhagavad-gītā by their own interpretation. That should not be done. Bhagavad-gītā as it is should be presented before the people of the world. They are suffering for want of Kṛṣṇa consciousness, and as soon as they become Kṛṣṇa conscious, their life becomes happy. So this is the mission of this society, International Society for Kṛṣṇa Consciousness.
