Ik Onkar

"[13] Ik Onkar has a distinct spelling in the Gurmukhi script[14] and the phrase is found in many Sikh religious scriptures and inscribed in places of worship such as gurdwaras.

[18] ੴ ਸਤਿ ਨਾਮੁ ਕਰਤਾ ਪੁਰਖੁ ਨਿਰਭਉ ਨਿਰਵੈਰੁ ਅਕਾਲ ਮੂਰਤਿ ਅਜੂਨੀ ਸੈਭੰ ਗੁਰ ਪ੍ਰਸਾਦਿ ॥ ਜਪੁ।। ਆਦਿ ਸਚੁ ਜੁਗਾਦਿ ਸਚੁ ਹੈ ਭੀ ਸਚੁ।। ਨਾਨਕ ਹੋਸੀ ਭੀ ਸਚੁ।। (Ik Oankaar Sati nāmu karatā purakhu nirabha'u niravairu akāla mūrati ajūnī saibha gura prasādi.

[20][21] According to Wendy Doniger, the phrase is a compound of ik ("one" in Punjabi) and onkar, canonically understood in Sikhism to refer to the "absolute monotheistic unity of God".

"[9] Onkar is, according to Wazir Singh, a "variation of Om (Aum) of the ancient Indian scriptures (with a slight change in its orthography), implying the seed-force that evolves as the universe.

"[24] Guru Nanak wrote a poem entitled Oankar in which, states Doniger, he "attributed the origin and sense of speech to the Divinity, who is thus the Om-maker".

[22] In 2019, Air India launched a direct flight from London to Amritsar with the phrase Ik Onkar printed in golden colour with a red background, on the tail of a Boeing 787 Dreamliner.
