Second part
For an experiment, can someone count to infinite? Impossible.
Guru Granth Sahib Ji reveals that many people have tried to find the limits of the infinite Lord but have failed. Therefore, God is described differently in Sikhism as compared to Hinduism.
In Sikhism, God's virtues and attributes are infinite and therefore cannot be counted and summed to equal a whole. In Hinduism, the various deities worshipped represent a particular attribute of god, in Sikhism only the whole is worshipped by acknowledging the vastness of God through the revealed Shabad, or the word of God.
This is where the concept of Naam comes in, something which does not exist in Hinduism and as such is a fundamental difference between the two faiths.
In Sikhism Naam is of the utmost importance, without it no liberation of the soul can take place.
What is the concept of Naam in Sikhism:
Naam is a very deep and integral part of Sikh belief. If one reads the English translation of Naam, it says Name. This is true but does not explain Naam completely. This is because Naam is the essence of God, in Sikhism God is Alakh, unfathomable, Apaar, infinite. Naam is not just the Name, but also, truthful living, truthful speaking, seeing the truth in every single being, breathing the truth, eating truth, totally immersed in the truth. In the first line of Guru Granth Sahib Ji, it says ‘SatNaam,’ that God's name is Truth.
Naam is also a way of life in Sikhism.
Let's do another experiment/demonstration, describe your mother.
A mother is someone who feeds you when you are hungry (sustainer), comforts you when you are sad (cherisher), protects you from danger and harm (protector). Now, when someone asks us, who is that woman? We say that is my mother. We do not say, that is the lady that protects me, feeds me, cherishes me, etc. The title of "Mother" is very informative and all the qualities associated with the name are understood without explanation.
So it is in Sikhism, the Naam, or the Name is very important. What is that name, SatNaam, the true name. The name is Waheguru, Satnam, Akal Purkh, Kartar, Narain, Nirankar etc. The Name describes the Lord and all the Lord's glorious attributes, infinite in number. Meditation and repartition of the Name brings one closer to the one God and all his attributes. In Sikhism one receives this Naam, from God, or from the Satguru, true guru, the perfect guru or the revealed word of God, Guru Granth Sahib Ji.
baani guru, guru hai baani - The word of God is Guru, and Guru is the word of God.
