Final answer:
Guru Amar Das introduced several institutional innovations to strengthen the unity of the Sikh Panth, such as the Manji system, Langar, and the Anand Karaj ceremony.
Step-by-step explanation:
Guru Amar Das (1479-1574) introduced several institutional innovations that strengthened the unity of the Sikh Panth (community). One of the key innovations was the establishment of the Manji system, which created a network of Sikh preachers and teachers known as Manjis. These Manjis played an important role in spreading the teachings of Sikhism and maintaining a sense of community among Sikhs. Another important innovation was the introduction of the Langar system. Langar refers to the community kitchen where free food is served to all visitors, regardless of their social or economic background. This practice of serving and sharing meals together helped break down social barriers and fostered a sense of equality and unity among Sikhs. Additionally, Guru Amar Das introduced the Anand Karaj ceremony, which is the Sikh marriage ceremony. This ceremony emphasized the equality of men and women and the importance of mutual love and respect in a marriage. By reforming the traditional marriage practices, Guru Amar Das aimed to strengthen family units and promote harmony within the Sikh community.
