Our Kṛṣṇa consciousness movement means: try to understand Kṛṣṇa. Simply if you try to understand . . . you cannot understand Kṛṣṇa fully. That is not possible. Kṛṣṇa is unlimited. But to our limited knowledge, whatever is possible, that is stated in the Bhagavad-gītā. As far as we can understand about Kṛṣṇa, if we simply understand Kṛṣṇa, His transcendental nature, His transcendental activities, divyam . . . janma karma me divyam (BG 4.9). Divyam means transcendental. It is not ordinary. Tattvataḥ, in truth, in fact. Then you become free from this janma-mṛtyu-jarā-vyādhi (BG 13.9). Very easy thing.
Therefore try to understand Kṛṣṇa. How you will understand Kṛṣṇa? Kṛṣṇa is so great. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ. Ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). You cannot understand Kṛṣṇa by these blunt material senses. That is not possible. You have to purify it. You have to purify it. Tat-paratvena nirmalam (CC Madhya 19.170). Simply by Kṛṣṇa consciousness, always thinking of Kṛṣṇa, all your senses will be purified. This is the process. Sevonmukhe hi jihvādau. And you can begin service with your tongue.
