This close contact enabled them to witness many of the spiritual principles evinced by these Great Masters translated into their everyday lives, which Spalding describes as acts that can be accomplished by anyone who comes to know his "TRUE" self.

Spalding's books have remained in print since his death and his stories have helped to popularize the concept of Ascended Masters which became a common meme in New Age and alternative religious movements during the later twentieth century.

Similar themes to Spalding can be seen in Ascended Master groups such as the Church Universal and Triumphant and the writings of Elizabeth Clare Prophet.

Spalding is named as an influence in the writings of New Age figures such as JZ Knight, Paul Baumann of the Methernitha sect and Father Divine.

American mystic Thane of Hawaii, founder of the Prosperos group, claimed in 1974 to have ghost-written several of Spalding's later books and accompanied him on his 1935 India tour.

There is a Vietnamese book, apparently first published in 1975, called Hành Trình Về Phương Đông by one Nguyên Phong.

In the story, Spalding is joined in India by a group of prestigious mystics and academics, including Paul Brunton and Walter Evans-Wentz.
