A tree species (Prosopis Cineraria) typically found in Rajasthan, Haryana, Uttar Pradesh, Punjab, Madhya Pradesh and Gujarat. Shri Mahuprabhiji typically recited the Bhagavat Purana under this tree where He could.
The Chhonkar tree has small leaves and branches with lots of stiff thorns. Shri Mahaprabhuji choose the Chhonkra tree to rest under as the thorns represent the evil behaviour of mankind and the little shade provided by the small leaves represents the materialistic life we enjoy. Those who shelter under Shri Mahaprabhuji's blessings, are salvaged from such things.
