What are the main similarities and differences between Sikhism and Jainism?

Respected Narinderjit Bajwa ji,
Waheguru ji ka Khalsa, Waheguru ji ki Fateh!

In response to your question, the undersigned requests you to kindly read about Jainism at a glance, by clicking on the link below:-

https://www.bbc.co.uk/religion/religions/jainism/ataglance/glance.shtml#:~:text=Jainism%20is%20a%20religion%20of,is%20non%20violence%20(ahimsa).

The biggest difference between Jainism and Sikhism is that there is no place of renunciation in Sikhism. A Sikh is expected to live in the present, without bothering about his past or future life, after death, if any. He is to live a disciplined family life, do his required duties, watch his deeds, earn honestly (Kirat Karo), Naam Japo (Remain one with Akalpurakh all the time) and Wand Chako (Share with the needy).

The Sikh is expected to get rid of falsehood (ਕੂੜ) and become a truthful person (ਸਚਿਆਰ) because Karam Khand is the door to Sachkhand (37th Pauri of Jap Bani).

The Sikh is generally non-violent but when need arises, he fights against oppression, tyranny and agression by all means and if it becomes necessary, he even lays down his life.

The Sikh is expected to respect and protect nature because the nature is the Sargun Saroop of Akalpurakh. Since what one eats has nothing to do with the religion, so he can be vegetarian or non-vegetarian, as per his choice.

Since there is no concept of salvation/emancipation, after death, so the Sikh is expected to live a life in which he gets rid of vices and become Jeevan Mukat.

The undersigned has tried to give major differences between Jainism and Sikhism but doesn’t claim perfection. If there are any shortcomings, please do point out the same, for improvement in future.

If you have any further questions, please do ask.

Regards,
Your Brother
