Final answer:
The spiritual birthplace of Khalsa is Anandpur Sahib, while Amritsar, home to the Golden Temple, is the central spiritual site for Sikhs around the world. Punjab is the homeland of the Sikh religion.
Step-by-step explanation:
The native place of all Sikhs, also known as Khalsas, cannot be exactly pinpointed to a single city as Sikhs hail from various regions. However, the spiritual birthplace of the Khalsa is Anandpur Sahib, and it is significant for the formalization of the religion. On the other hand, the Golden Temple, located in Amritsar, stands as the most important spiritual site in Sikhism. Amritsar is a city where Sikhs from around the world unite in their faith and is considered the epicenter of Sikh religious activity. The Punjab region is widely regarded as the homeland of the Sikhs, where their religion, founded by Guru Nanak Dev, was established and flourished.
