At Rai about thirty of his shorter works are said to have been composed.
The head of the Church (Zara-Shushtrotema) had his seat at Rai in Media and was the first person in the state next to the king.
The guru before his death at Kiratpur, on the margin of the Sutlej, instructed his grandson and successor, Guru Har Rai, to retain two thousand two hundred mounted soldiers ever with him as a precautionary measure.
Har Rai was charged with friendship for Dara Shikoh, the son of Shah Jahan, and also with preaching a religion di s tinct from Islam.
