He also helped Gandhi articulate and elucidate his vision of India in the Hind Swaraj which was written primarily for Mehta (who is indicated as the "Reader").

[1] Mehta was born in Morvi, the youngest of four brothers, into a wealthy Jain business family with roots in Kathiawar, Gujarat.

An older brother, Revashankar "Jhaveri" Jagjivan Mehta who had been a lawyer of repute to the Raja of Morvi later set up a jewellery shop in Kalpadevi.

After studies at Morbi and Rajkot, Pranjivan went to the Grant Medical College and received a LMS with a gold medal in 1886.

Mehta was involved with the Burmese nationalists, and numerous social activities such as the Hindu Social Club, the Burma Provincial Congress Committee and was the founder of the Anglo-Gujarati newspaper United Burma edited by V. Madanjit who earlier published the Indian Opinion from Durban.
