Vishnu is the One True God, who is proclaimed in the Vedas. He is the transcendental, Omnipotent, Omniscient, and Omnipresent Supreme Lord. Vishnu is the One True God and Ruler of all the Universes and all Material and Spirtual Creation. He is the eternal, ever-youthful, and Supremely blissful Supreme Lord. Vishnu created the material Universes by breathing them out of Himself. All the Universes in the material world were created by him 4 Quadrillion years ago. Shortly after this creation the first Brahma was born from a lotus flower emanating from him. Brahma being the first human inquired about where he was and spent most of his life trying to find Vishnu. Brahma emanated from a lotus flower out of Vishnu's navel. Brahma could not find the limits of the Supreme Lord Vishnu. At the beginning of creation 4 Quadrillion years ago, Vishnu created the Vedas and imparted it to Brahma. Later Brahma passed the Vedic Knowledge on to his sons Shiva and Narada and they passed this ancient Vedic Knowledge on to the human race. This Vedic Knowledge has been in existence for 4 Quadrillion years because Vishnu imparted the Vedas to the first Brahma at his birth, and according to the Mahabharta there have been seven brahmas so far. Each Brahma lives for 311 trillion, 40 billion years and a period of equal unmanifestation lasts another 311 trillion, 40 billion years. Thus there are 622 trillion, 80 billion years between the births of each Brahma. Since the Vedas were first imparted to the first of Seven Brahmas that would make the Vedas 7 times 622 trillion, 80 billion years old or approximately 4 Quadrillion years old.
Sikhism on Vishnu
Sikhism instructs to worship the One true God, the Creator of all that exists. Sikhs do not worship the Gods of the Hindu Pantheon, idols of stone or any other material.
Though the Guru Granth Sahib and the Dasam Granth refer to the words Shiva, Vishnu, Krishna, Allah and other names familiar to the Hindus and Muslims, it uses these names in a different context.
Some Bani from the Guru Granth Sahib:
God is the creator of all. “He created air, water, fire, Brahma, Vishnu and Shiva” (Guru Granth Sahib, 504).
“He created Brahma, Vishnu and Shiva, who act according to His Will” (Guru Granth Sahib, 948).
“The performance of countless millions of other devotions is not even equal to one devotion to the Name of God” (Guru Granth Sahib, 1163). “Those who serve Shiva and Brahma cannot find the limits of God” (Guru Granth Sahib, 516).
The ones who serve any other instead of God cannot attain salvation. Salvation is granted only by God. “Everyone must serve the One Lord, who created Brahma, Vishnu and Shiva. O Nanak, the One True Lord is permanent and stable. He does not die, and He is not born” (Guru Granth Sahib, 1130).
By the order of God, Brahma obtained a body. By the order of God, Shiva was born. By the order of God, Vishnu was born. Everything is created by God. God, who made Shiva a yogi. God, who gave Brahma the kingdom of Vedas. God, who has shaped the entire universe. Is the one we salute. They consider that Shiva is God. They are unaware of the Supreme Primal Lord. (Benti Chaupee Sahib).
Sikhi teaches that their is only one God. The Guru Granth Sahib Ji is the Holy Scripture of the Sikhs. Sikhs bow their head in their Gurdwaras to Guru Granth Sahib as a sign of respect but Sikhs do not worship the scriptures. Considered the Eleventh spiritual teacher of the Sikhs which shows the way to meet God. Guru Nanak instructs that idol worship will not lead one to salvation. Worshipping sculptures of stone will not help one to meet God.
Guru Nanak Dev said that for sikhs:
The Guru is Shiva, the Guru is Vishnu and Brahma; the Guru is Paarvati and Lakhshmi. Shiva, Brahma and the Goddess of Beauty, ever adorned, sing.
Remember Vishnu again and again; By remembering Vishnu you will never suffer defeat. (Gauri Bawan Akhri Kabir, p. 342)
At whose door should I take refuge, Vishnu, Shiva, an adept, a Muni or Indra. One may give you kingdom, the other may take you to heaven, rare one among a million may ask for salvation. (Kalyan M. 5, p. 1322)
O Lord! Vishnu and Lakshmi could not know you besides four Vedas, Smritis and Puranas. (Dhanasari Kabir, p. 691)
Kishan (connoting Vishnu) is always busy in incarnating himself, then with whose help one may ferry across the world-ocean ? (Wadhans M. 3, p. 559)
last but not least
He created air, water and fire, Brahma, Vishnu and Shiva - the whole creation.
