In 1970 Sears attended a statewide conference in February in Bradenton, Florida, and another tape of a talk of his was sent to a youth conference in Indiana and a summer school in Seattle in June, however Sears was actually out of the country. In May he attended the French national convention and in August an (Indian) oceanic conference in Mauritius on the way to a task assigned by the Universal House of Justice. It had requested that Sears tour Iran with Marguerite, and their travels were aided by the Iranian National Spiritual Assembly, several of whom were to disappear in a few years. They were able to visit many sites important in the History of the Baháʼí Faith — the homes of the Báb and Baháʼu'lláh, the site of the Conference of Badasht, the Siyah-Chal, the fortress of Maku, the site of the Battle of Fort Tabarsi, and the place of the Báb's execution — all despite various levels of harassment. Sears published "The Prisoner and the Kings" following this trip. His next Baháʼí event was the Naw-Ruz opening of the Baháʼí new year celebration in a number of events in Los Angeles in March, despite the troubles of the February 1971 San Fernando earthquake, drawing participants from New Mexico, Nevada and Arizona. The talks and slides of the event were recorded. While he was away in Iran a taped message was presented at the US national convention, a general discussion tape on spiritual assemblies as an institution of the religion was released, again Sears' "God Loves Laughter" was donated to a library and a tape of a talk of his was used in a public meeting in Indiana.
