We are not part of Waheguru in this body, the merging occurs when our spirituality is at a high enough level:
(Original post by Rouz)
1) I've read in Sikhism everybodies soul is a part of God's soul, is that correct? Is this a physical thing, i.e there is Gods soul and we all have a small part of it? So in essence, we all have some "divine" in us?
"One who is not touched by pleasure, pain, greed, emotional attachment and egotistical pride. Nanak says, listen mind: he is the very image of God. One who is beyond praise and slander, and looks upon gold and iron alike. Nanak says, listen mind: know that such a person attains salvation. One who is not affected by pleasure or pain, and looks upon friend and enemy alike. Nanak says, listen mind: know that such a person attains salvation"
(Guru Granth Sahib, Ang 1427)
Oh and God doesn't have a "soul." God is God, and nothing else.
It is a spiritual merging
2) I also read the aim of life is to avoid rebirth/reincarnation and merge back with God. Again, is this a literal and physical merging or does it mean something else?
"One's soul blends with the (Waheguru's) Light, and one becomes totally perfect."
(Guru Granth Sahib, Ang 846)
No. Waheguru is omnipresent within the creation, but that does not mean that Waheguru
is the creation.
3) I think i also read that sikhs believe God created the world out of himself or a part of himself? Is that true?
This analogy should clear things up: supposing I mix sugar with water; the sugar is now within the water, but this does not mean that the sugar is the water - this would clearly be absurd. This is similar to the nature of Waheguru.
The believe that God is the creation is a Hindu belief, which was forced into Sikhism under the British rule:
"The fanatic and corrupt Hindu Mahants installed idols in the Gurdwaras and introduced Hindu rites and rituals which were denounced and renounced by the Sikh Gurus. In this way the Mahants brought Sikh religion under the evil influence of Hinduism and muddled it greatly."
(The Gallant Defender, Dr. A.R. Darshi, pp. 25)
4) Do you believe the Gurus received revelation from God?
"Waaho! Waaho! This is the Bani, the Word, of the Formless Lord. There is no other as great as He is."
(Guru Granth Sahib, Ang 515)
"O GurSikhs, know that the Bani, the Word of the God, is true, absolutely true. The Creator Lord Himself causes the Guru to chant it."
(Guru Granth Sahib, Ang 308)
"Falsehood will come to an end, O Nanak, and Truth will prevail in the end."
(Guru Granth Sahib, Ang 953)
“Waheguru gave me His Hukam (Order) to sing His Praises day and night. Waheguru, my Lord and Master summoned me, His minstrel, to the True Mansion of His Presence. (Waheguru,) the Image of True Praise and Glory, gave me the Siropaao, robe of honour. The spiritual-life giving Name, Amrit Naam, the True Name, which gives eternal spiritual life, has become my sustenance.”
(Guru Granth Sahib, Ang 150)
"O Lalo! As the Lord’s word comes to me so I deliver it."
(Guru Granth Sahib, Ang 722)
"I myself know not what to say; all I speak is what the Lord commands."
(Guru Granth Sahib, Ang 763)
Loads; For example, the expanse of the universe according to Sikhism:
What proof do you have for that,
"There are planets, solar systems and galaxies. If one speaks of them, there is no limit, no end. There are worlds upon worlds of His creation. As He commands, so they exist. He watches over all, and contemplating the creation, He rejoices."
(Guru Granth Sahib, Ang 8)
"There are billions of regions and planets. There are billions of moons, suns and stars"
(Guru Granth Sahib, Ang 275)
"Many millions are the fields of creation and galaxies. Many millions are the skies and solar systems... He has expanded His expansion of creation many times. Forever and ever, He is the One, the One Universal Creator."
(Guru Granth Sahib, Ang 276)
There is a wealth of further material I could go into here, but you get the idea.
I think that these descriptions are truly remarkable, but don't just take my word for it!
"The Guru Granth Sahib of all the world religious scriptures, alone states that there are innumerable worlds and universes other than our own. The previous scriptures were all concerned only with this world and its spiritual counterpart. To imply that they spoke of other worlds as does the Guru Granth Sahib, is to stretch their obvious meanings out of context. The Sikh religion is truly the answer to the problems of the modern man."
(Sikh Review, Rev. H. L. Brawshaw)
Yes, but I think an important distiction needs to be made here. The Gurus could not perform miracles of their own accord, it was Waheguru who was performing the miracles through them:
did they do any miracles?
"That alone is miraculous power, which the Carefree Lord spontaneously bestows."
(Guru Granth Sahib, Ang 650)
An example of this is still present at Hassan Abdal, Pakistan.
This is a boulder that was thrown on Guru Nanak by Wali Kandhari, because he was jealous of the Guru. Guru Nanak stopped the boulder with the palm of his hand alone. It, and a spring of water which Guru Nanak produced, still stand there today, where they are enclosed in the Gurdwara Panja Sahib.
