Basic Teachings of Sri Guru Nanak Dev Ji
There is one God; the creator off everything, Waheguru is the supreme soul. Waheguru is our true mother and father.
Salvation is when our soul merges back into Waheguru
Waheguru is unborn, self-existent, immortal, truth, without fear, without hate. The world is a fake drama, like a dream. Waheguru is beyond birth and death.
Deeds and devotion determine salvation, not caste, status and colour etc
We must respect all beings and faiths. (Guru Nanak Dev Ji had a Muslim and a Hindu accompany him throughout his travels when spreading his message of truth)
Forceful conversion into any faith is an evil deed. Every person has the right to freely think, and freely pursue a faith of their choice. (In 1675, Sri Guru Teg Bahadur Ji, the 9th Sikh Guru gave his life for another faith to protect this principle)
Women have equal status as men and should not be treated as inferior (Sri Guru Granth sahib Ji, says that women are the ones that give birth to kings and saints, why should they be treated as inferior?)
Despite having comfort, luxury and prosperity, there is no true contentment without spiritual and moral foundation.
Human life form is a precious opportunity to get salvation; it will go to waste, if it is squandered away in false egocentric attachment with materialism.
Equality of all is important, all our souls are from the same Lord, therefore everyone should have equal rights, regardless of sex, status, religion, colour etc. We should have no discrimination, and should treat people the way we would want to be treated.
We must work and earn honestly.
We should help the poor and needy, a minimum of 10% of our earnings should be given to charity.
We must be kind and helpful.
We must reject rituals, superstitions, omens, incantation (magic spells) and amulets.
We should share and never be greedy or selfish.
A Sikh should only believe in Sri Guru Granth sahib Ji as the true guru. If they do not they are not a Sikh.
