Sadhu Thanwardas Lilaram Vaswani (Sindhi: साधू थांवरदास लीलाराम वास्वाणी; Sādhū Thāṃvaradās Līlārām Vāsvāṇī) (25 November 1879 – 16 January 1966)[3][4] was an Indian educationist who started the Mira Movement In Education and set up St. Mira's School in Hyderabad, Sindh, and later moved to Pune after 1949.

As a boy, he first learned about the sacred texts called the Upanishads from Brahmabandhav Upadhyay, a Brahmin from Bengal who adopted Christianity, but in 1907 he underwent prayashchitta (expression of reparation in Hindu custom) through a public ceremony to return into Hinduism.

Later in his lifetime, Sadhu Vaswani was recognized as an accomplished proponent of the Upanishads and a skilled interpreter of the Bible and the Qur'an.

His mother sought to arrange a marriage for her son but Vaswani vowed to remain a brahmachari and never to marry.

[7][8] In July 1910, when Vaswani was 30 years old, he and his guru, Sri Promotholal Sen, sailed from Mumbai to Berlin.

In 1948, Vaswani reluctantly migrated to India from Sindh, which lay in the newly formed state of Pakistan.

[10] Prior to his exile, he and his followers had stirred controversy after prasad was distributed as usual at his weekly meeting that took place two days after the death of Pakistan's founder, Muhammad Ali Jinnah.

Upon his motion and under his influence the Sind Political Conference of the Indian National Congress passed a resolution regarding the Non-cooperation program.
