Sikh means to seek the truth, and the core truth of the Sikh gurus is:
Existence alone exists dreaming forever (as indivisible consciousness, a non-spatial self-existent spiritual reality).
The Ocean is in the drop. The world is imagined within the subject (as consciousness, existence, a spirtual Being without space).
Life is a completely subjective experience, entirely from the view of the subject who alone exists (as indivisible consciousness).
This is summed up by mystics as "Raab di leela" - It's all God's play (the play of consciousness, indivisible spirit, Existence Itself).
Your atma (soul) and Paramatama (the Infinite, consciousness) are always one (as consciousness is indivisible).
The clue lies in our dreams. Each night we dream (project) a world which seems to be just as real and solid as the one we wake up to.
On waking we realize it never existed, except as a dream in our consciousness. If we ask of what that world in our dream was made of?
The answer is nothing (no space, material or movement), it was simply imagined (projected like a movie) within our consciousness.
Why does consciousness dream? Why do you dream at night? Its the nature of consciousness to dream, infinite Self experiencing (play).
Using the same Sanskrit words, the Sikh gurus, the Buddha and Hindu mystics reveal the 3 states and awakening to the 4th:
At night you dream with eyes closed. During day you dream with eyes open. The underlying reality in both is your consciousness.
So the Sikh gurus define the core goal of a Sikh (truth seeker) as: "Aapna mool pashaano" (realize your Self as consciousness).

By continually reading books men commit mistakes and by wearing religious garbs, they take great pride. What does it avail to man to bathe at a place of pilgrimage, when the filth of self-conceit (ego mind) is within his mind.

Men ruin themselves by their search without (outside) while the Thing is in the sacred place of their home (consciousness). The pious receive it in their lap, whilst the perverse miss it through ego. 63.

Having created the universe, that Lord (consciousness) abides therein. 83: 62-65.
People think of religious laws and regulations. But without understanding God, how can they swim across duality? Make faith thy bowing and let the conquest of mind be thy aim of life. In whatever direction I see, I find God present in that direction. 84: 71-94.
By Guru's instruction, one recognizes his own Self, and the light of the Lord's Name comes into him. The true man practices truth. 86: 42-55.
The foolish and ignorant man recognizes not the Creator who is within his Self (as consciousness). Because of the love of duality, he instructs the world and himself understands not Divine Knowledge. He loses his life in vain and dies and is born again and again. 86: 6-18.

Attached to ego and duality, man has forgotten the Master (his own consciousness). 86: 92-96.
Nanak, he whom God unites with Himself separates not from Him and is easily absorbed in Him. He is the man of God's sect who knows the Auspicious Master and by Guru's grace recognizes his own Self. He restrains his wandering mind, and brings the one God in his heart-home. He remains dead whilst alive and repeats the Name of God. Sublime is such a devotee. He is absorbed in the True Lord O' Nanak. 88
Know thus O Nanak, that the True One is all by Himself (as consciousness). That Pure One is all in all Himself. He is neither established nor created by anyone. 2:67
Make brotherhood with all the highest sect of yogic order, and deem conquering of Self the conquest of the world. 6:81
Thou O' venerable and unique Lord God art uninterrruptedly contained in all the hearts and in everything (as consciousness). Some are the givers, and some the mumpers. All these are thy wondrous frolics. Thou thyself art the Giver,and Thyself the Enjoyer. Beside Thee, I know of none other. 11:2
Thou art the river and all are in Thee. Beside Thee, there is none else. 11:51
As seconds, minutes, hours, quarters of a day, lunardays, weekdays, months and several seasons spring from the lone sun. So many forms originate from the Creator, O Nanak! 12:29

The One Lord is within thy home (as consciousness) and the One without. He Himself is found within all places. 45:67
The soul and body (waves) all belong to Him (Ocean) and there is no support except that of Him. 36:29
This world is asleep in an illusion and in sleep the night (life) passes away. Some He delivers of His own will, and unites with Himself. He Himself abides within man's mind and drives off love of illusion.
He Himself bestows honor and causes Himself to be understood through the Guru. The Lord alone is the Giver for all. He corrects those in error. He Himself has misled some and has attached them to duality. Under Guru's instruction God is attained and man's soul merges with the Supreme Soul. 36:100
