Does god exist?

Sāt samand kī masi karau, lekhani sab banrāi।
Dhartī sab kāgad karau, tau harī guṇ likhyā na jāi॥

- Kabir Granthavali (Pg 261)

Even if I make the water of the seven seas into ink and all the forests into pens and the entire earth into paper, even then the qualities of God cannot be written because God is endowed with infinite attributes.

According to Hindu scriptures, the universe is composed of five elements—sky, air, fire, water, and earth.
And the word 'Bhagwan' itself reflects this connection to the elements.

Bha - Bhumi (Earth)
Ga - Gagan (Sky)
Va - Vayu (Wind)
Aa - Agni (Fire)
Na - Neer (Water)

Shrimad Bhagwat Mahapuran (2.9.30)
Shri Bhagwan said - (O Chaturnaanan!) I tell you about my knowledge which is the most secret, which is endowed with science (experience) and is accompanied by devotion, and its means, listen.

Shrimad Bhagwat Mahapuran (2.9.31)
As many forms as I have, as my existence is and whatever my forms, qualities, and actions, by my grace you should learn the knowledge of the same.

Shrimad Bhagwat Mahapuran (2.9.32)
I was the only one before the creation of the universe, apart from me, there was none of the gross, subtle, or natural, even after creation I was there, this world (visible) is also me and whatever remains at the time of destruction is also me.

Shrimad Bhagwat Mahapuran (2.9.33)
That due to which the soul perceives its real meaning even when it is not there and does not perceive its meaning even when it is there, know that to be my Maya, like Abhaas (illusory knowledge of two moons in one moon) and like Rahu (Rahu is not visible even when it is there in the solar system).

Shrimad Bhagwat Mahapuran (2.9.34)
Just as the five great elements enter and leave the physical objects in the form of cause and effect, similarly I also enter and leave these physical objects (this is my existence).

Shrimad Bhagwat Mahapuran (2.9.35)
For those who wish to know the soul, the only thing worth knowing is that from the beginning of creation to the end of creation, the one who always remains the same in all three worlds (heaven, earth, hell) and all three times (past, present and future), is God.

Shrimad Bhagwat Mahapuran (2.9.36)
Practice this belief with utmost concentration of the mind; O Brahma, you will never have the pride of being the creator in the various creations of the Kalpa.
Lord Swayambhuva Manu (Lord Brahma's son) left the kingdom after getting detached with all desires and pleasures. He went to the forest with his wife Shatarupa to do penance(tapasya). He did severe penance for a hundred years by standing on one leg on the earth on the banks of river Sunanda and used to praise God in this way every day.

Manuji used to say-

Shrimad Bhagwat Mahapuran (8.1.9)
The one whose consciousness makes this world conscious, but to whom this world cannot donate consciousness; the one who remains awake even in the apocalypse whom it cannot know, but who knows it - he is the Supreme Soul.

Shrimad Bhagwat Mahapuran (8.1.10)
This entire world and all living and non-living creatures living in this world - all are filled with that Supreme Soul. Therefore, one should not get attached to any material thing of the world and should use it only for the sustenance of life by abandoning it. Greed should be completely abandoned.
Well, who owns these worldly possessions?

Shrimad Bhagwat Puraan (8.1.11)
God is the witness of everything. He cannot be seen by the intellect, eyes, and other senses. But His power of knowledge is unbroken. Take refuge in that self-illuminating, God who resides in the heart of all living beings.

Shrimad Bhagwat Puraan (8.1.12)
He who has no beginning and no end, then how can there be a middle? He who has neither his own nor others, and neither outside nor inside, is the beginning, end, middle, own and others, outside and inside - everything of the universe.

The universe exists because of His existence. He is the infinite, real, true, Supreme Brahma.
