So to purify the eyes we require... That is meditation, how to search out. He is within my heart. Anywhere you sit down, you can see God, provided you have got the eyes to see. Premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti [Bs. 5.38]. Those who are saintly persons, they are twenty-four hours seeing God. They have nothing, no other business than to see God. But they have got eyes to see. That is the difference. Ordinary persons, they have no eyes. Therefore they cannot see God. But those who have developed consciousness, Kṛṣṇa consciousness, purified eyes, they can see always, twenty-four hours. They don't see anything else except God. Because God is everything. Whatever we see, if we have two eyes to see, then we can see God in every second, every moment. How? Oh, that you can practice
In the Bhagavad-gītā it is said raso 'ham apsu kaunteya: [Bg. 7.8] "I am the taste of water." Now, you are drinking water hundreds times. So as soon as you taste water, how nice it is, you can immediately see God, Kṛṣṇa, "Oh, here is Kṛṣṇa. Here is Kṛṣṇa." So how do you say that "Can you show me Kṛṣṇa?" You can see. Here is the process. You adopt it. You taste water, and when you enjoy the taste, that taste is Kṛṣṇa. Kṛṣṇa says, "I am this taste." Then where is the difficulty to see Kṛṣṇa? There is no difficulty. The people say, "Can you show me God?" God is everywhere, in every moment, in every step. You do not like to see Him. That is the difficulty. Raso 'ham apsu kaunteya prabhāsmi śaśi-sūryayoḥ. "I am the sunshine and moonshine." Who has not seen sunshine? Everyone has seen. From the very morning, we see sunshine, and at night also, when there is darkness, there is no sun, we see moonshine. So sunshine, moonshine—Kṛṣṇa says, prabhāsmi śaśi-sūryayoḥ. So as soon as I see the sunshine and moonshine, I see God. What is the difficulty? Śabdaḥ khe. When there is some sound, rumbling sound in the sky, khe... Khe means sky. Kṛṣṇa says, "I am the sound." So as soon as you hear even the sound of airplane, that is also God. Puṇyo gandhaḥ pṛthivyāṁ ca. When you smell a nice flower, that smell is Kṛṣṇa. So you can remember immediately Kṛṣṇa.
