Which notable figure's popularity surged in the 1960s due to Eastern cultural interest?

The correct choice is the Dalai Lama, whose popularity surged significantly in the 1960s as Western interest in Eastern philosophies and cultures grew. This period marked a time when many individuals in the West were exploring alternative spiritual practices, away from traditional Western religious structures. The Dalai Lama, as the spiritual leader of Tibetan Buddhism, became a prominent symbol of peace and compassion during this time.

His advocacy for non-violent resistance and the promotion of Buddhist principles resonated with the counterculture movement, which sought peace and spiritual enlightenment. Various events, including the Tibetan uprising in 1959 and his subsequent exile to India, brought international attention to his cause. As a result, he began to travel extensively to share his message, leading to increased visibility and popularity in the West.

The other individuals in the options played significant roles in promoting Eastern philosophies, but the Dalai Lama's presence and activities during the 1960s positioned him uniquely as a bridge between Eastern spirituality and Western audiences seeking new ideals, making him a standout figure during this period.
