Sikhs believe in one God. He is the same for all people of all religions.
Guru Nanak Dev, the first Sikh Guru, taught three fundamental principles:
| There is one God. | Ik Onkar |
| His Name is Truth. | Satnam |
| He is the Creator. | Karta |
| He is present throughout His Creation. | Purakh |
| He fears none. | Nirbhao |
| He hates none. | Nirvair |
| His existence is immortal. | Akal Murat |
| He is not born, nor does He die. | Ajuni |
| He is self-illuminated. | Saibhang |
| He is realized through the grace of the Guru. | Gur prasad |
