What is the meaning of marriage according to Sikhi?

Respected Ajuni Kaur ji,
Waheguru ji ka Khalsa, Waheguru ji ki Fateh!

In response to your question about meaning of marriage in Sikhi, the undersigned wants to say that, you would be already aware that in Sikhism ‘marriage (ਵਿਆਹ)’ is called ‘Anand Karaj (ਅਨੰਦ ਕਾਰਜ) and significant spiritual and religious importance is attached to this act.

It is not merely a physical and legal contract but a sacrament, a union of two souls. The spiritual goal of any Sikh is to merge his or her soul (ਆਤਮਾ) with Akalpurakh and in marriage, the couple vows to help each other towards this goal.

With the example of a worldly marriage performed, on a material plane, between a man and a woman, the Guru Granth Sahib explains in the four ‘Laavaan’, (Pannas 773-774 of Guru Granth Sahib), as to how one can join (marry or link), with the Higher Consciousness within.

Thus, marriage, in the Sikh Way of life, is supposed to be an unbreakable Spiritual Union or Unity of two minds into one. Unity between wife and husband’s mind (i.e. thinking-Soch) provides constancy, faithfulness, dependability, reliability, loyalty, fidelity, firmness, true love, companionship or friendship, strength to endure, and resistance to disintegration of the entire family. Thus it provides stability for the entire family.

Guru Amar Daas Jee in Raag Soohee highlights this required Unity as follows: –

ਧਨ ਪਿਰੁ ਏਹਿ ਨ ਆਖੀਅਨਿ ਬਹਨਿ ਇਕਠੇ ਹੋਇ ॥ ਏਕ ਜੋਤਿ ਦੁਇ ਮੂਰਤੀ ਧਨ ਪਿਰੁ ਕਹੀਐ ਸੋਇ ॥ ॥੩॥ (ਪੰਨਾ 788)

ਅਰਥ: ਜੋ (ਸਿਰਫ਼ ਸਰੀਰਕ ਤੌਰ ਤੇ) ਰਲ ਕੇ ਬਹਿਣ ਉਹਨਾਂ ਨੂੰ ਅਸਲ ਇਸਤ੍ਰੀ ਖਸਮ ਨਹੀਂ ਆਖੀਦਾ; ਜਿਨ੍ਹਾਂ ਦੇ ਦੋਹਾਂ ਜਿਸਮਾਂ ਵਿਚ ਇੱਕੋ ਆਤਮਾ ਹੋ ਜਾਏ ਉਹ ਹੈ ਇਸਤ੍ਰੀ ਤੇ ਉਹ ਹੈ ਪਤੀ।੩।

Thus Anand Karaj is a means to learn helping each other, to attain together a balanced life of self-fulfillment, Spiritual Upliftment and Self-knowledge, leading to a purposeful life.

As per teachings of Guru Granth Sahib, the importance of Family life is that both husband and wife first become Gurmukhs themselves and live their lives, as per teachings of Guru Granth Sahib, and then try their best to ensure that their children also become Gurmukhs, so that the life of children also becomes successful.

Hope it helps. If you have any further questions, please do ask. If you find any deficiencies, please point out the same for improvement in future.

Your Brother
