This is a part of the cacred vedic text these texts are called upanishads it takes years to understand them but this is a part that may make sense to you
EIGHTH PRAPATHAKA
FIRST KHANDA
1. Harih, Om. There is this city of Brahman (the body), and in it the palace, the small lotus (of the heart), and in it that small ether. Now what exists within that small ether, that is to be sought for, that is to be understood.
2. And if they should say to him: 'Now with regard to that city of Brahman, and the palace in it, i.e. the small lotus of the heart, and the small ether within the heart, what is there within it that deserves to be sought for, or that is to be understood.
3. Then he should say: 'As large as this ether (all space) is, so large is that ether within the heart. Both heaven and earth are contained within it, both fire and air, both sun and moon, both lightning and stars; and whatever there is of him (the Self) here in the world, and whatever is not (i.e. whatever has been or will be), all that is contained within it.'
4. And if they should say to him: 'If everything that exists is contained in that city of Brahman, all beings and all desires (whatever can be imagined or desired), then what is left of it, when old age reaches it and scatters it, or when it falls to pieces?' Then he should say: 'By the old age of the body, that (the ether, or Brahman within it) does not age; by the death of the body, that (the ether, or Brahman within it is not killed. That the Brahman) is the true Brahma-city (not the body). In it all desires are contained. It is the Self, free from sin, free from old age, from death and grief, from hunger and thirst, which desires nothing but what it ought to desire, and imagines nothing but what it ought to imagine. Now as here on earth people follow as they are commanded, and depend on the object which they are attached to, be it a country or a piece of land,
6. 'And as here on earth, whatever has been acquired by exertion, perishes, so perishes whatever is acquired for the next world by sacrifices and other good actions performed on earth. Those who depart from hence without having discovered the Self and those true desires, for them there is no freedom in all the worlds. But those who depart from hence, after having discovered the Self and those true desires, for them there is freedom in all the worlds.
SECOND KHANDA
1. 'Thus he who desires the world of the fathers, by his mere will the fathers come to receive him, and having obtained the world of the fathers, he is happy.
2. 'And he who desires the world of the mothers, by his mere will the mothers come to receive him, and having obtained the world of the mothers, he is happy.
3. 'And he who desires the world of the brothers, by his mere will the brothers come to receive him, and having obtained the world of the brothers, he is happy.
4. 'And he who desires the world of the sisters, by his mere will the sisters come to receive him, and having obtained the world of the sisters, he is happy.
5. 'And he who desires the world of the friends, by his mere will the friends come to receive him, and having obtained the world of the friends, he is happy.
6. 'And he who desires the world of perfumes and garlands (gandhamalya), by his mere will perfumes and garlands come to him, and having obtained the world of perfumes and garlands, he is happy.
7. 'And he who desires the world of food and drink, by his mere will food and drink come to him, and having obtained the world of food and drink, he is happy.
8. 'And he who desires the world of song and music, by his mere will song and music come to him, and having obtained the world of song and music, he is happy.
9. 'And he who desires the world of women, by his mere will women come to receive him, and having obtained the world of women, he is happy.
'Whatever object he is attached to, whatever object he desires, by his mere will it comes to him, and having obtained it, he is happy.
THIRD KHANDA
1. 'These true desires, however, are hidden by what is false; though the desires be true, they have a covering which is false. Thus, whoever belonging to us has departed this life, him we cannot gain back, so that we should see him with our eyes.
2. 'Those who belong to us, whether living or departed, and whatever else there is which we wish for and do not obtain, all that we find there (if we descend into our heart, where Brahman dwells, in the ether of the heart), There are all our true desires, but hidden by what is false. As people who do not know the country, walk again and again over a gold treasure that has been hidden somewhere in the earth and do not discover it, thus do all these creatures day after day go into the Brahma-world (they are merged in Brahman, while asleep), and yet do not discover it, because they are carried away by untruth (they do not come to themselves, i.e. they do not discover the true Self in Brahman, dwelling in the heart).
3. 'That Self abides in the heart. And this is the etymological explanation. The heart is called hrid-ayam, instead of hridy-ayam, i.e. He who is in the heart. He who knows this, that He is in the heart, goes day by day (when in sushupti, deep sleep) into heaven (svarga), 1.e. into the Brahman of the heart.
4. 'Now that serene being which, after having risen from out this earthly body, and having reached the highest light (self-knowledge), appears in its true form, that is the Self,' thus he spoke (when asked by his pupils). This is the immortal, the fearless, this is Brahman. And of that Brahman the name is the True, Satyam,
5. This name Sattyam consists of three syllables, sat-ti-yam. Sat signifies the immortal, t, the mortal, and with yam he binds both. Because he binds both, the immortal and the mortal, therefore it is yam. He who knows this goes day by day into heaven (svarga).
FOURTH KHANDA
1. That Self is a bank, a boundary, so that these worlds may not be confounded. Day and night do not pass that bank, nor old age, death, and grief; neither good nor evil deeds. All evil-doers turn back from it, for the world of Brahman is free from all evil.
2. Therefore he who has crossed that bank, if blind, ceases to be blind; if wounded, ceases to be wounded; if afflicted, ceases to be afflicted. Therefore when that bank has been crossed, night becomes day indeed, for the world of Brahman is lighted up once for all.
3. And that world of Brahman belongs to those only who find it by abstinence -- for them there is freedom in all the worlds.
FIFTH KHANDA
1. What people call sacrifice (yagna), that is really abstinence (brahmakarya). For he who knows, obtains that (world of Brahman, which others obtain by sacrifice), by means of abstinence.
What people call sacrifice (ishta), that is really abstinence, for by abstinence, having searched (ishtva), he obtains the Self.
2. What people call sacrifice (sattrayana), that is really abstinence, for by abstinence he obtains from the Sat (the true), the safety (trana) of the Self.
What people call the vow of silence (mauna), that is really abstinence, for he who by abstinence has found out the Self, meditates (manute).
3. What people call fasting (anasakayana), that is really abstinence, for that Self does not perish (na nasyati), which we find out by abstinence.
What people call a hermit's life (aranyayana), that is really abstinence. Ara and Nya are two lakes in the world of Brahman, in the third heaven from hence; and there is the lake Airanimadiya, and the Asvattha tree, showering down Soma, and the city of Brahman (Hiranyagarbha) Aparagita, and the golden Prabhuvimita (the hall built by Prabhu, Brahman).
Now that world of Brahman belongs to those who find the lakes Ara and Nya in the world of Brahman by means of abstinence; for them there is freedom in all the worlds.
SIXTH KHANDA
1. Now those arteries of the heart consist of a brown substance, of a white, blue, yellow, and red substance, and so is the sun brown, white, blue, yellow, and red.
2. As a very long highway goes to two places, to one at the beginning, and to another at the end, so do the rays of the sun go to both worlds, to this one and to the other. They start from the sun, and enter into those arteries; they start from those arteries, and enter into the sun.
3. And when a man is asleep, reposing, and at perfect rest, so that he sees no dream, then he has entered into those arteries. Then no evil touches him, for he has obtained the light (of the sun).
4. And when a man falls ill, then those who sit round him, say, 'Do you know me? Do you know me?' As long as he has not departed from this body, he knows them.
5. But when he departs from this body, then he departs upwards by those very rays (towards the worlds which he has gained by merit, not by knowledge); or he goes out while meditating on Om (and thus securing an entrance into the Brahma-loka). And while his mind is failing, he is going to the sun. For the sun is the door of the world (of Brahman). Those who know, walk in; those who do not know, are shut out. There is this verse: 'There are a hundred and one arteries of the heart; one of them penetrates the crown of the head; moving upwards by it a man reaches the immortal; the others serve for departing in different directions, yea, in different directions.'
