"The śānti, peace, real peace, can be achieved simply by understanding that God is the proprietor and God is the enjoyer of everything—that conception." Bhoktāraṁ yajña-tapasāṁ sarva-loka-maheśvaram. And suhṛdaṁ sarva-bhūtānām: "And He is the friend, most intimate friend, well-wisher friend of everyone." And He is seated with everyone's heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati. (BG 18.61). "My dear Arjuna, the Supreme Lord is seated with every living entity."
So according to Vedic literature, Upaniṣad, we understand that the Supreme Lord in His localized aspect, He is all-pervading. He is present everywhere. Not only that He is present in the church, but He is outside church, everywhere. It is stated in this Brahma-saṁhitā, aṇḍāntara-stha-paramāṇu-cayān (Bs. 5.35). "He is present even within the atom." That is omnipresence. So He is present within you. It is not that you have to search out God anywhere else, but you have to . . . you can search out within yourself. And that searching process is called yoga. Our this subject matter today is yoga. That means to search out your self.
Meditation means you have to meditate upon what you are. Are you this body? Are you this finger? Are you this head? You analyze one after another, you will find that you are not this. Then you analyze your mind, whether you are mind, you will find you are not mind also. If you analyze your beyond mind, your intelligence, then you will find that you are not intelligence even. Beyond that intelligence you are sitting.
These things are very nicely explained in the Bhagavad-gītā. And when you find out your self, that is self-realization. And as you become self-realized, the symptoms become that you become jolly and free of all anxieties. So long you are not self-realized, you are full of anxieties. That is the nature, material nature.
Not only we, human being, even birds, beasts, they are also full of anxieties. You give some eatables to the pigeons, to the birds, he will eat and look like this, "Oh, somebody may not come, kill me." Yes. This is the nature. Now, you are American people, supposed to be the richest country. Oh, you have also many anxieties. You are not free from anxiety. You are also afraid of China or Russia or somebody else.
So how you can be free from anxiety? That is yoga system. If you actually practice yoga system . . . yoga system, the whole Bhagavad-gītā is yoga system. It is said in the Fourth Chapter that imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). The Lord says that "This yoga system I first of all spoke to the sun-god." Imaṁ vivasvate. Vivasvata means . . . the sun-god's name is Vivasvān. Imaṁ vivasvate yogaṁ proktavān aham avyayam, vivasvān manave prāhu (BG 4.1): "And Vivasvān, he explained this yoga system to his son, Manu." Now, if we calculate the age of Manu, it comes to some millions. At least forty millions of years before, it was spoken.
