He was allowed to return to Lithuania in 1959 and worked as a lecturer and journalist and continued his anthropological studies, but his past as a political prisoner prevented him from taking a more prominent position.

[2] In Kaunas, Poška lived in a dormitory maintained by Žiburėlis society[6] and worked odd jobs, including construction, while attending an evening school.

[4] In 1926, when the first Lithuanian radio station opened in Kaunas, Poška hosted a regular Esperanto-language program Nia anguleto.

[7] They financed the trip by giving lectures on Esperanto, Lithuania, and other topics as well as submitting articles and photos to Lithuanian and foreign press.

While visiting Mohenjo-daro, he met professor Biraja Sankar Guha who invited him to work at the Anthropological Laboratory of the Indian Museum.

[5] The Lithuanian press widely reports that in 1933, Poška accompanied Oxford University professor Aurel Stein on an anthropological expedition to the Taklamakan Desert in Central Asia.

Poška and his team gathered somatometric measurements and other anthropological data on the lifestyle, habits, and customs of the local inhabitants.

He also befriended Suniti Kumar Chatterji who later embarked on a comparative study The Balts and the Aryans, exploring the commonalities between India's Vedic and the Baltic pagan rites.

[9] Published as a monograph by the Indian Institute of Advanced Study in 1968, this Chatterji's book is dedicated to, among others, Antanas Poška.

[11] Friendship with the renowned Indian Esperantist Sinha Laksmiswar led Poška to Shantiniketan where he had a chance to interact with Rabindranath Tagore.

In Turkey, he wrote an article on the Kurds and their aspirations for which he was arrested and escorted 318 km (198 mi) in chains to Bulgaria in June 1936.

Poška was awarded the Life Saving Cross by the President of Lithuania in 1998[1] and was recognized as the Righteous Among the Nations by the Government of Israel in 2000.

[6] For refusing the orders from Juozas Žiugžda to destroy books published before the Soviet occupation, Poška was arrested in June 1945[2] and sentenced to imprisonment in a forced labor camp in Siberia.

His academic nature won him positions at several ethnographic museums of Central Asia in 1949–59, but due to his status of a political prisoner he could not assume leading posts and had trouble publishing his works.

[3] After his return home Poška worked as a lecturer, a correspondent of several newspapers, and the chairman of the reestablished Vilnius Esperantist Club in 1964–69.

[4] As a former political prisoner, he remained suspect to Soviet authorities and was not allowed to continue academic activities or publish his books until the Perestroika reforms in 1985.

For example, in 1960, together with biologist Tadas Ivanauskas, he visited the Tigrovaya Balka Nature Reserve in Tajikistan[20] and later hitchhiked to Leningrad and Moldova.

[3] It was a five-week motorbike ride to the Mount Elbrus in the Caucasus Mountains, via the Georgian Military Road to Georgia, Armenia, Azerbaijan and Sukhumi on the Black sea.

[6] His major work, the eight-volume book on his journey to India From the Baltic Sea to the Bay of Bengal, was published by his supporters already after his death.

[12] After his visit to Lithuania in 1966, Dr. Suniti Kumar Chatterji agreed to help Poška recover his PhD dissertation from London and secure his degree.

[12] In 2014, the Lithuanian Embassy in New Delhi took the initiative of approaching the University of Calcutta with a proposal to posthumously award Poška with a doctoral degree.

[1] Most of these are articles published in the press of Lithuania and other countries (India, USSR, Poland, UK) as well as in international Esperanto magazines.
