In Patna there lived two Nawab brothers Rahim Bakhsh and Karim Bakash. They were rich landlords and were owner of many villages.
They also owned many business establishments.
Once Guru Tegh Bahadur stayed in their garden.
The Guru liked this Garden very much. He considered that garden very suitable for meditation.
Actually the tress of that garden had withered. But by Guru's grace the dry Bagh became lush and Green with plantlife.
Seeing these miracle two brothers became his devotees.
At the birth of child Guru, these two brothers presented many gifts to the Guru. They loved him very much and were coming daily to have glimpse of the prophet.
The child prophet also had great affection for them. They donated that Garden and village for the maintenance of the Langar.
