Pandurang Sadashiv Sane (Marathi pronunciation: [paːɳɖuɾəŋɡ səd̪aːʃiʋ saːne] pronunciationⓘ ; 24 December 1899 – 11 June 1950), also known as Sane Guruji (Guruji meaning "respected teacher") by his students and followers, was a Marathi author, teacher, social activist and freedom fighter from Maharashtra, India.

The family was relatively well off during Sane's early childhood, but their financial condition later deteriorated, leading to their house being confiscated by government authorities.

His mother's death due to a lack of medical facilities as well as his inability to meet her at her deathbed would haunt Sane Guruji for the rest of his life.

Sane completed his primary education in the village of Dondaicha, in the Shindkheda taluka in Dhule district.

However, on the recommendation of one of his friends, and with support from his parents, he enrolled at the Aundh Institution, which provided free education and food to poor students.

Back in Palgad, one night he overheard his parents' conversation where his father expressed concern over his son's dedication to education.

Enraged and hurt by his father's suspicion, he immediately traveled to Pune and enrolled as a student at the Nutan Marathi Vidyalaya.

Sane resigned from his school job to join the Indian Independence Movement when Mahatma Gandhi started the Dandi March in 1930.

He was imprisoned by the British authorities in the Dhule Jail for more than fifteen months for his work in the Civil Disobedience Movement.

Bhave's work Gītā Pravachane (Marathi: गीता प्रवचने) was an outcome of the notes Sane had made while imprisoned.

[7] He recognised the importance of learning Indian languages, particularly in the context of the problem of national integration; and started the Antar Bharati movement.

[8] Sane played a crucial role in the spread of the Indian National Congress presence in rural Maharashtra, particularly in Khandesh.

[12] In response to Mahatma Gandhi's promise to Babasaheb Ambedkar during Poona Pact that he will spend the rest of his life campaigning for the removal of untouchability, Sane took up the cause as well.

[10][13] In the post-independence period, Sane became increasingly disillusioned over the possibilities of eliminating inequality from Indian society.

His most well-known work in Marathi literature include Śhyamchi Aai which has been translated in almost all the Indian languages as well as in Japanese and English.
