Difference / Diversity is an illusion - Srimad Bhagavata
'Brahma satyam, jagat mithya, jivo brahmaiva' - all in this one chapter of the Bhagavatam
In this chapter of the Bhagavata, Sri Krishna himself teaches the knowledge of Self to his father Vasudeva:

The qualities of nature like sattva and its effects like the universe are imagined/superimposed in Brahman. Therefore, these, the universe, do not really exist in you: (jagat is only an appearance, mithya)
This is the purport of the Upanishadic statement 'neha nanasti kinchana'. There is no diversity or difference in Brahman; difference, bheda, multiplicity, is merely an appearance. It's clear that this doesn't mean 'rejecting the difference in the form and qualities of the Supreme Self'. Here, it denies the existence of the universe, which is the effect of Prakriti, in the Supreme Self.** Also, since it says that the three gunas and its evolutes are kalpita in Brahman, it also follows that the ananta kalyana gunas of Brahman are not absolute as they are all products of the three gunas. Each and every guna like sarvajnatva, sarva shaktitva, parAkramatva, sarva niyAmakatva, karma phala daatrutva, etc., can be seen to be the products of the combination of the three gunas and not otherwide.
The universe has only dependent reality, paratantra satyatvam; independent reality, svatantra satyatvam, belongs to Brahman alone. Therefore, the universe must depend on Brahman's reality. Here, it's said that the universe is superimposed, imagined, a mere appearance in the Supreme Self. Thus, it's concluded that the universe has no existence at all. The vyApti is: рдпрджреНрдпрддреНрдкрд░рд╕реНрддреНрдорд╛рджрд╕реНрддрд┐рддреНрд╡рдВ рдкреНрд░рд╛рдкреНрдиреЛрддрд┐ рддрддреНрддрдиреНрдорд┐рдереНрдпрд╛, рд╕реНрд╡рдкреНрдирд░рдЬреНрдЬреБрд╕рд░реНрдкрд╛рджрд┐рд╡рддреН | That which has to depend on something other than itself for its very existence is mithya, like the dream, the snake superimposed on the rope, etc.
In this case, Brahman becomes non-transactional, avyavahaaryam. The Mandukya Upanishad describes Brahman as 'avyavaharyam' (non-transactional) and 'prapanchopashamam' (cessation/absence of the universe). The universe doesn't really exist. If the universe existed, Brahman would be considered its cause in vyavaharika terms. Since the universe itself is imaginary, Brahman has absolutely no relation to the universe and thus becomes free from the universe.
The father Vasudeva continues:

In this flow of the qualities, guNas, of maya, the ignorant, unable to understand the sukshmaam gatim - the subtle, universe-free, quality-less, nirguna, nature of the Paramatman - remain in the illusion that the world is real.

Assuming the state of a jiva and thinking 'This is me, these are all mine', with the sense of 'I' and 'mine' in the body and others, O Supreme Self, you have bound this world.

The Self is one, self-luminous. Eternal. Different from non-Self. Without attributes. This is the declaration of Brahma eva satyam. It appears as many due to imagined qualities. Just as the five elements manifest in their effects like pots etc., and disappear during dissolution, Brahman, through imagined qualities, experiences the worldly states like birth and death in bodies which are its effects. This is mere appearance.
