Edward started his primary education under a Buddhist scholar monk and then attended St. Mary's College, Negombo.

[2] Edward developed a keen interest in Buddhism and gradually began working as a true nationalist, while he was a law student.

He changed his name to E.de S. Walisinghe and started teaching at the Sunday Dhamma school at Ananda College, Colombo.

Walisinghe Harischandra joined the Mahabodhi Society, which had been established by Anagarika Dharmapala, a prominent figure of Sri Lankan (Sinhala) Buddhist nationalist movement.

He made up his mind to stop this desecration and published a booklet named, the Sacred City of Anuradhapura and sent a copy to King George V. In this book he pointed out that the Crown representatives despoiled Buddhist Holy places and appealed to him to protect their sanctity.
