You have read the scriptures. So I will not waste your time by quoting scriptures. I will instead quote Sri Ramakrishna on this topic. It might clear up the confusion.
"No one can say with finality that God is only 'this' and nothing
else. He is formless and again He has forms. For the bhakta He assumes
forms. But He is formless for the jnani, that is, for him who looks on
the world as a mere dream. The bhakta feels that he is one entity and
the world as another. Therefore God reveals Himself to him as a
Person. But the jnani – the Vedantist, for instance - always reasons,
applying the process of 'Not this, not this'. Through this
discrimination he realizes, by his inner perception, that the ego and
the universe are both illusory, like a dream. Then the jnani realizes
Brahman in his own consciousness. He can not describe what Brahman
is."
"Do you know what I mean? Think of Brahman, Existence-Knowledge-Bliss
Absolute, as a shore-less ocean. Through the cooling influence as it
were, of the bhakta's love, the water has frozen at places into blocks
of ice. In other words, God now and then assumes various forms for His
lovers and reveals Himself to them as a Person. But with the rising of
the sun of knowledge, the blocks of ice melt. Then one doesn't feel
any more that God is a Person, nor does one see God's forms. What He
is can not be described. Who will describe Him? He who would do so
disappears. He cannot find his 'I' anymore."
[The Gospel of Sri Ramakrishna, October 28, 1882, p 148]
"What Brahman is cannot be described. All things in the world - the
Vedas, the Puranas, the Tantras, the six systems of philosophy - have
been defiled, like food that has been touched by the tongue. Only one
thing has not been defiled in this way, and that is Brahman. No one
has ever been able to say what Brahman is."
[The Gospel of Sri Ramakrishna, August 5, 1882, p 102]
"Brahman is beyond word and thought. It is said in the Vedas that
Brahman is of the nature of Bliss. It is Satchidananda. ..... In Samadhi one
attains the knowledge of Brahman - one realizes Brahman. In that state
reasoning stops altogether, and man becomes mute. He has no power to
describe the nature of Brahman."
[The Gospel of Sri Ramakrishna, August 5, 1882, p 102-103]
Sri Ramakrishna also says,
" Brahman is without comparison. It is impossible to explain Brahman
by analogy. It is between light and darkness. It is light, but not the
light we perceive, not material light."
[The Gospel of Sri Ramakrishna, October 16, 1883, p 307]
Then again Brahman has also been compared to a chameleon by Sri
Ramakrishna:
"Listen to a story. Once a man entered a wood and saw a small animal
on a tree. He came back and told another man that he had seen a
creature of a beautiful red color on a certain tree. The second man
replied:'When I went into the wood, I also saw that animal. But why do
you call it red? It is green.' Another man who was present
contradicted them both and insisted that it was yellow. Presently
others arrived and contended that it was grey, violet, blue and so
forth and so on. At last they started quarreling among themselves. To
settle the dispute they all went to the tree. They saw a man sitting
under it. On being asked, he replied,'Yes, I live under this tree and
I know the animal very well. All your descriptions are true. Sometimes
it appears red, sometimes yellow, and at other times blue, violet,
grey, and so forth. It is a chameleon. And sometimes it has no color
at all. Now it has a color and now it has none.'
In like manner, one who constantly thinks of God can know His real
nature; he alone knows that God reveals Himself to seekers in various
forms and aspects. God has attributes; then again He has none. Only
the man who lives under the tree knows that the chameleon can appear
in various colors, and he knows, further, that the animal at times has
no colors at all. It is the others who suffer from the agony of futile
arguments........ God reveals Himself in the form which His devotee
loves most."
[The Gospel of Sri Ramakrishna, October 28, 1882, p 149]
