A few kilometres from Mandi in Himachal Pradesh lies Gurudwara Rewalsar Sahib, a site of deep historical and spiritual importance. It commemorates the visit of Guru Gobind Singh Ji, the tenth Sikh Guru, who came here to engage with the hill chieftains and encourage them to unite against the growing tyranny of the Mughal emperor Aurangzeb.

Though Guru Ji, in his divine wisdom, already knew their intentions, he held the meeting to reveal their true character to all. The chieftains initially agreed to join the cause and even expressed willingness to partake in Amrit, symbolizing spiritual unity and equality. However, they demanded to be served Amrit in a separate Khanda-Baata (iron vessel), insisting on preserving their social status.

Guru Gobind Singh Ji rejected this outright, declaring that Amrit is one and the same for everyone and must be received from a single vessel. When they refused, the proposed alliance fell apart. Their inability to embrace equality ultimately exposed their pride and divisions. Many of these kings later sided with Aurangzeb and took arms against Guru Ji.

The Gurudwara built at this site by the devotees stands beside Rewalsar Lake, a tranquil body of water believed to possess healing properties. Constructed from stone and reached by climbing 108 steps, the Gurudwara draws devotees from various faiths, who visit this spiritually rich site with great reverence.

Rewalsar is also significant in Hindu and Buddhist traditions. According to Hindu mythology, the Pandavas created the lake during their exile, and it remains sacred for its spiritual and curative qualities. For Buddhists, Rewalsar is where Guru Padmasambhava (Guru Rinpoche) is believed to have meditated and attained enlightenment. He is credited with spreading Buddhism in Tibet, making this place an important pilgrimage site for Tibetan Buddhists.
