Nandalal Bose’s ink drawing portrays Sanghamitra, the daughter of Emperor Aśoka, as she carries a sacred Bodhi Tree sapling to Sri Lanka. Her calm demeanour highlights her vital role in spreading Buddhism. The artwork emphasises the tree’s significance as a symbol of Buddha, showcasing Sanghamitra’s dignity and serenity with expressive lines and an ethereal quality. In the 19th or 20th year of Aśoka’s reign, Sanghamitra travelled to Sri Lanka with ten nuns during King Devanampiya Tissa’s rule. She planted the Bodhi sapling in Mahameghavana garden in Anuradhapura and taught essential Buddhist texts, establishing the Bhikkhuni Order and ordaining Princess Anula and her companions. Sanghamitra lived in the Upasika-vihara, a nunnery comprising twelve buildings, and King Devanampiya Tissa later constructed additional nunneries around Thuparama.
