Just like we see sometimes the hills from our room. Here there are many hills in Los Angeles. But they are not distinct. When you are seeing the hills from a distant place, it looks like something cloudy. But if you go still further towards the hill, you'll distinctly find that there is something, hill. And if you come to the hill, then you'll find so many persons are working there, so many houses are there. There are streets, motorcars, everything, all varieties.
So similarly, when one wants to know the Absolute Truth by his teeny brain—"I shall make research to find out the Absolute Truth"—then you'll have vague idea, impersonal idea. And if you become a meditator, then you will find that God is situated within your heart.
Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ (SB 12.13.1). The yogīs, the real yogīs, they, by meditation, they see viṣṇu-mūrti within the heart. And those who are devotees, they meet the Supreme Person face to face, just like we are meeting face to face, talk face to face, serve directly. The Supreme Personality of Godhead orders that "You supply Me this," and he supplies. That is the difference.
So samo 'haṁ sarva-bhūteṣu (BG 9.29). He's equal to everyone. Now it is up to you to understand Him according to your capacity. So Kuntī also says the same thing in this verse: samaṁ carantaṁ sarvatra. Samaṁ carantam. Carantam means moving. He is moving everywhere, outside, inside—simply we have to make our eyes clear to see Him. That is devotional service, to make our senses purified to perceive the presence of God. God is present everywhere. Antar bahiḥ. Antaḥ means within, and bahiḥ means without. "Those who are less intelligent, they simply try to find out God within, and those who are advanced in intelligence, they can see You within and without." That is the difference.
Meditation is meant for the less intelligent class of men. Meditation means you have to control the senses. yoga practice means yoga indriya-saṁyama. Our senses are very restless. By yoga practice, by, I mean to say, practicing different āsana, so mind is controlled, the senses are controlled. Then we can concentrate upon the form of Viṣṇu within our heart. That is yoga system. Or those who are too much in bodily concept of life, for them the yoga system is recommended, practicing the bodily exercise, and find out the Supreme Lord within the heart. But bhaktas, those who are devotees, who are still more advanced, they don't require to control their senses separately, because to be engaged in devotional service means controlling the senses.
Suppose you are engaged in worshiping the Deity, cleansing the room, in decorating the Deity, in making foodstuff for Deity, everything nicely. So your senses are already engaged. Where is the chance of your senses being diverted? The senses are already controlled. Because my senses, hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate (CC Madhya 19.170). Bhakti means simply to engage the senses in the service of this master of the senses. Hṛṣīkeśa means master of the senses, and hṛṣīka means senses. So now our senses are engaged for sense gratification. Sarvopādhi, upādhi yuktaḥ. So "I am this body, so I must satisfy my senses." This is the contaminated stage of life. But when one comes to the understanding that, "I am not this body; I am spirit soul, part and parcel of God," so my senses, spiritual senses, should be engaged in the service of the Supreme Spiritual Being. That is wanted.
