"In that personal abode of the Lord, the material modes of ignorance and passion do not prevail, nor is there any of their influence in goodness. There is no predominance of the influence of time, so what to speak of the illusory, external energy. It cannot enter that region. Without discrimination, both the demigods and demons worship the Lord as devotees.
"The inhabitants of the Vaikuntha planets are described as having a glowing sky-bluish complexion. Their eyes resemble lotus flowers, their dress is of yellowish colour, and their bodily features are very attractive. They are just the age of growing youths, they all have four hands, they are all nicely decorated with pearl necklaces with ornamental medallions, and they all appear to be effulgent."
In Srimad Bhagavatam (10.14.2) the demigod Brahma, now freed from illusion, speaks the following prayer:
"My dear Lord, neither I nor anyone else can estimate the potency of this transcendental body of Yours, which has shown such mercy to me and which appears just to fulfil the desires of Your pure devotees. Although my mind is completely withdrawn from material affairs, I cannot understand Your personal form. How, then, could I understand the happiness You experience within Yourself."
In the Mundaka Upanisad (2.2.9) it is said:
"The self-realised souls know that the spiritual world is effulgent, pure, glorious, and never touched by matter."

The chief historical proponent of such “I am God”ism philosophy was Sripad Shankaracharya. Shankaracharya lived and preached throughout India in the eighth century. The preaching of Shankaracharya and his followers was so strong that, practically speaking, it drove Buddhism out of India. Today, throughout India and the world, Shankaracharya's teachings (or slight variations of them) are still having a tremendous influence on people.
In Calcutta, India, for example, we can see the ridiculous sight of a starving, sore-infested man meditating on the side of the road: “I am God. I am God.” In America and Europe, you'll find many so-called yogis and gurus who are directly or indirectly in Shankaracharya's line of “I am God” ism teachers.

Lord Caitanya Mahaprabhu quoted these words of Srimad-Bhagavatam (1.2.11):
"Learned transcendentalists who know the Absolute Truth call the non dual substance Brahman, Paramatma, or Bhagavan."
In the Narada-pancaratra it is said:
"In the midst of the spiritual world's splendour resides the Supreme Personality of Godhead, His peerless form dark and handsome."
In the Brahma-samhita (5.1) it is said:
"Krsna who is known as Govinda, is the supreme controller. He has an eternal, blissful, spiritual body. He is the origin of all, for He is the prime cause of all causes."
In the Isa Upanisad (mantra 8) it is said:
"Such a person must factually know the greatest of all, who is unembodied, omniscient, beyond reproach, without veins, pure, and uncontaminated, the self-sufficient philosopher, who has been fulfilling everyone's desires since time immemorial."
In the Brahmanda Purana, the demigods offer these prayers glorifying Lord Krsna, who stays in Sri Radha's heart:
"You are the Supreme Brahman, whom the Madhyandina recension of the Vedas glorifies with the words 'sad eva saumyedam
"The Vedas glorify You with the words, 'dve vidye veditavye'. You are the Supreme Brahman described in the Vedas. We offer our obeisances to You again and again.
"The Brhad-aranyaka Upanisad describes You with the words, 'ekam evadvitiyam'. You are the Supreme Brahman described in the Vedas. We offer our obeisances to You again and again.
"The Vedas glorify You with the words, 'eko vai purusah'. You are the imperishable Supreme Person described in the Vedas. We offer our obeisances to You again and again."
