Guru Govind Singh is the most influential and the last leader for the Sikhs. His contributions to the Sikh community will always make everyone bow to his personality. He was the one who had started the concept of Khalsa (The pure). Khalsa played a key role in protecting the Sikhs long after his death during the nine invasions of Panjab. Khalsa's are Sikhs which have undergone the sacred Amrit Ceremony initiated by the 10th Sikh Guru, Guru Gobind Singh. The Khalsa order was initially created on Baisakhi Day March 30 1699, with Guru Gobind Singh baptizing 5 Sikhs and then, in turn, asking the five Khalsa's to baptize him. Following this, the Guru personally baptized thousands of men and women into the Khalsa order.

The Khalsa baptism ceremony is undertaken as part of one’s own personal spiritual evolution when the initiate is ready to fully live up to the high expectations of Guru Gobind Singh. All Sikhs are expected to be Khalsa or be working towards that objective. The ceremony of the Khalsa’s is about drinking to be considered Amrit which is made mixing sugar water stirred with a dagger in the presence of 5 Khalsa Sikhs as well as the Guru Granth Sahib (their sacred book). The people who follow the Khalsa will need to follow the below-mentioned rules:-

1. They are not allowed to remove any hair from any part of thy body.
   
2. They shall not use tobacco, alcohol or any other intoxicants.
3. They are not allowed to eat the meat of an animal slaughtered the Muslim way.
4. They shall never commit adultery. The initiate is required to wear the physical symbols of a Khalsa at all times as well as follow the Khalsa Code of Conduct.

Guru Gobind Singh's teachings have a great impact on Sikhs. He stood against the Mughal Rulers and fought against injustice. In 1699, Guru Gobind Singh baptized five men from the lower caste as his Five Beloveds, endowing them with courage and devotion to God. His dedication to God, his fearlessness and his desire to protect the people from being oppressed made Guru Gobind Singh established the Khalsa, a military force of saint-soldiers. Under Guru Gobind Singh's guidance and inspiration, the Khalsa followed a strict moral code and discipline. Through his courage, the people rose against the oppression of the Mughal ruler in India. Aside from being a spiritual and a military leader Guru Gobind Singh was also a writer. Before his death in 1708, he declared Sikhism's Holy Scripture, Guru Granth Sahib to be the permanent Sikh Guru. In Guru Govind Singh Jayanti; thousands of devotees assemble in Golden Temple (holiest Gurudwara of Sikhism) of Amritsar to participate in prayers and sing devotional songs in the memory of their one of the greatest Sikh Guru.
