Hey Kizzy,
There's a lot of info about Sikhism on the net lol but anywayz lemme help you.
Khalsa:
Khalsa (Punjabi: ਖਾਲਸਾ, literally "Pure") refers to the collective body of all baptized Sikhs. The Khalsa was originally established as a military order of "saint-soldiers" on 30 March 1699, by Guru Gobind Singh, the tenth Sikh Guru. It was the name given by the Guru to all his disciples baptized in the Amrit Sanchar ceremony.
The symbolic meaning of Khalsa translates as "belonging exclusively to Guru Gobind Singh". Guru Gobind Singh describes in his book, the Dasam Granth the qualities of Khalsa:[1]
"The Khalsa is the reflection of my form, The Khalsa is my body and soul, The Khalsa is my very life.... ....Our enemies are vanquished by the steadfastness of Khalsa, Unlike countless others, we are adorned by the Khalsa."
Khalsa Sikhs can be identified with their Turbans, Steel Braclets and Uncut Hair. Sikhs were given the Five Ks after the tenth Sikh Guru, Guru Gobind Singh the Baisakhi Amrit Sanchar in 1699. Every baptised Sikh must follow The Five Ks they are not merely symbols but commitment of faith which collectively form the external visible symbols to identify and clearly and outwardly advertise and display one's commitment.
The word Khalsa is derived from Arabic word khālisa[h] خالصة ("pure/devoted").
Ok basically, ur sikh right so you should know when we see someone jinnha ne amrit shakeya ae, like they have taken Amrit, they are baptized. You can recognize a Sikh who has taken Amrit because they wear a Kirpan around themselves, a small sword, they don't cut there hair, they wear a Kadha, and so on...Once they have taken Amrit, they are pure, because they follow all the rules or are supposed to follow all the rules about doing all the prayers, always telling the truth... Once they do that they belong to the Khalsa. But, not every Sikh takes Amrit, even though we are supposed to, but its extremely difficult for most people to follow all the rules, so they choose not to take the responsibility. That's why Sikh babies are not baptized right away, everyone is given a right to choose, since the rules and codes are very strict.
Secondly, Sri Guru Granth Sahib ji, its of course the sacred/holy book of the Sikhs. We do our prayers from it; It is the eternal Guru, or teacher. It is the living embodiment of the Ten Gurus. Basically Sri Guru Granth Sahib ji is a collection of hymns by the Sikh Gurus, and many Muslim and Hindu Saints. Originally, the collections were put together by Bhai Gurdas ji and later by Bhai Mani Singh ji, but they didn't write them, they just put them all together. :
"The Adi Granth was first compiled by the fifth Sikh Guru, Guru Arjan Dev (1563-1606), from hymns of the first five Sikh Gurus and other great saints of the Hindu and Muslim traditions.[5] The original scribe of the Adi Granth was Bhai Gurdas and later Bhai Mani Singh. After the demise of the tenth Sikh Guru many handwritten copies were prepared for distribution by Baba Deep Singh.
The 'Guru Granth Sahib' is a voluminous text of 1430 pages, compiled and composed during the period of Sikh Gurus, from 1469 to 1708.[1] It is compiled in the form of hymns written in praise of God, which describe what God is like[5] and the right way to live. Written in the Gurmukhi script, it is written predominantly in Punjabi but includes cursory use of other languages including Braj, Old Punjabi, Khariboli (Hindi), and Persian."
The main message i guess that you can sum up is:
1. All peoples of the world are equal
2. Women are equal
3. One God for all
4. Speak and live truthfully
5. Control the five vices
6. Live in God's hukam (Universal Laws)
7. Meditate on the name of God (Remember God)
8. Practice Humility, Kindness, Compassion, Love, etc
Hope that helped, good luck!!
And if it all falls apart, I will know deep in my heart, the only dream that mattered had come true. In this life, I was loved by you.
