“But you cannot see Me with your present eyes. Therefore I give to you divine eyes by which you can behold My mystic opulence.” (Lord Krishna, Bhagavad-gita, 11.8)

“Avyakta means unmanifested. Not even all of the material world is manifested before us. Our senses are so imperfect that we cannot even see all of the stars within this material universe. In Vedic literature we can receive much information about all the planets, and we can believe it or not believe it. All of the important planets are described in Vedic literatures, especially Shrimad-Bhagavatam, and the spiritual world, which is beyond this material sky, is described as avyakta, unmanifested. One should desire and hanker after that supreme kingdom, for when one attains that kingdom, he does not have to return to this material world.” (Shrila Prabhupada, Bhagavad-gita, Introduction)

“But you cannot see Me with your present eyes. Therefore I give to you divine eyes by which you can behold My mystic opulence.” (Lord Krishna, Bhagavad-gita, 11.8)

“For the purpose of confusing the citizens, Rama spoke to the charioteer as follows: ‘Mounting the chariot alone, O Charioteer, beginning by facing north, go quickly for a while and then turn the chariot back again.

“Wherever there is Krishna, the master of all mystics, and wherever there is Arjuna, the supreme archer, there will also certainly be opulence, victory, extraordinary power, and morality. That is my opinion.” (Bhagavad-gita, 18.78)

“In the Gaura-ganoddesha-dipika (115) it is said that the two brothers Jagai and Madhai were formerly the doorkeepers named Jaya and Vijaya, who later became Hiranyaksha and Hiranyakashipu. Jagai and Madhai were born in respectable brahmana families, but they adopted the professions of thieves and rogues and thus became implicated in all kinds of undesirable activities, especially woman-hunting, intoxication and gambling. Later, by the grace of Lord Chaitanya Mahaprabhu and Shri Nityananda Prabhu, they were initiated, and they got the chance to chant the Hare Krishna maha-mantra.” (Shrila Prabhupada, Chaitanya Charitamrita, Adi 10.1.20 Purport)

“But if you have faith still in the words of Lord Shiva, my dear king of the demons, then why don’t you make an experiment by putting your hand on your head? If the benediction proves false, then you can immediately kill this liar, Lord Shiva, so that in the future he will not dare to give out false benedictions.” (Lord Narayana in the guise of a mendicant speaking to Vrikasura, Krishna, The Supreme Personality of Godhead, Volume 2, Chapter 33)
