Bhai Bidhi Chand Ji was from Sursingh in Amritsar district, a highway robber by his own account, who came to Guru Arjan Dev Ji and was accepted. He became one of Guru Hargobind Sahib Ji's commanders.
The episode he is known for is the recovery of two horses. Two fine horses sent as offerings to the Guru from Kabul were seized by the Lahore authorities. He entered the Lahore fort twice in disguise, once as a grass cutter and once as an astrologer, and took them out.
It is a comic story and it is told as one, and it is also a straightforward account of a raid on a fortified provincial capital by one man.
He fought at Amritsar, Kartarpur and the other actions of Guru Hargobind Sahib Ji's reign.
The Bidhi Chand dal of the Nihangs, based at Sur Singh, takes its lineage from him and keeps horses.
The accounts describe him as a highway robber before he came to Guru Arjan Dev Ji, and the transformation is the part the tradition emphasises.
The two horses had been intercepted on their way to the Guru and taken into the Lahore stables. He took them out on two separate occasions by disguise rather than by force.
A dera of his line continues at Sursingh in Tarn Taran district. He was also sent as an envoy to Kabul, which is the less told part of the service.
