So Kṛṣṇa says in the Bhagavad-gītā, raso 'ham apsu kaunteya. He's teaching how to become Kṛṣṇa conscious. It's not difficult at all. He says... Everyone drinks water. Who can say that "I do not drink water"? Then, then why you have not seen Kṛṣṇa? Kṛṣṇa says, raso 'ham apsu kaunteya [Bg. 7.8]. So as soon as you taste, you understand what is Kṛṣṇa. What is the difficulty? If you try to understand Kṛṣṇa in this easy way, gradually Kṛṣṇa consciousness will develop.

Kṛṣṇa consciousness is there in everyone's heart, because everyone is part and parcel of Kṛṣṇa. Just like part and parcel of gold is gold. There may be some dusty cover, but it has to be cleansed. That's all. Then it becomes gold. Similarly, everyone is Kṛṣṇa conscious. But on account of his association with matter, he, he's thinking that he's different from Kṛṣṇa. Otherwise every one of us... Mamaivāṁśo jīva-bhūtaḥ [Bg. 15.7]. Everyone is Kṛṣṇa's part and parcel. Part and parcel of Kṛṣṇa means part and parcel of gold. As you understand part... A little drop of sea water, it is also, contains the same ingredients. Similarly, we have also got the same ingredients, as Kṛṣṇa has got. The difference is He's big. Aṇor aṇīyān mahato mahīyān. We are small, particle.
