"All things, material and spiritual, originate from one source and are related as if they were one family. The past, present, and future are all contained in the life force. The universe emerged and developed from one source, and we evolved through the optimal process of unification and harmonization."
-- Morihei Ueshiba

O'sensei was a very devote follower of shinto. he actually set up several shrines and would got on pilgramages often. actually during his life O'sensei was an activist of sorts and was almost put to death on the main land with his spiritual teacher and a couple of his other followers. lucky for us that did not happen. there is a great book titled "the spiritual foundations of aikido" by wiliam gleason that speaks about it. also you can check into the life of and beliefs of Wanisaburo Deguchi, O'senseis spiritual teacher, and a hugely controveseial figure in japanese recent history, who brought to him many of the beliefs that he wove into his art. there are other books too but i can not remember thier names i will write them down next time i am at the dojo and post them here for you.

"The Art of Peace that I practice has room for each of the world's eight million gods, and I cooperate with them all. The God of Peace is very great and enjoins all that is divine and enlightened in every land."

Yeah I'd say heavily influenced by shinto as a youth and Omoto Kyo as an adult - but ultimately, after the creation of Aikido, it's my opinion if you asked him he would speak something like the above quote, transcending religion all together.

Kaiso (Founder/ O'sensei) stated that the movements of Aikido were given by SARUTAHIKO-NO-O-KAMI and ways to become like SARUTAHIKO-NO-O-KAMI ( Primal Earhtly Kami, Kami of Guidance-Protection-Positiveness and Aikido's Guardian Kami) . The Main Shrine of this Kami is Tsubaki Grand Shrine in Mie (one of Japan's Oldest Shrines). The Mitama of O'Sensei as well as that of Nidai Doshu (Kisshomaru Sensei) are enshrined in Tsubaki Gyomando (Buddhist Hall of Tsubaki Grand Shrine).

The Mission of Aikido is also tied to the Kami: AMANOMURAKUMOKUKISAMUHARARYUOHAYATAKEMUSUNOOKAMI (The Aiki Okami) regarding TakemusuKami: Yaoyorozu-no-kamitachi-O is that the Yaoyorozu-no-O-kami are the unlimited deities who work to establish the land of Onogorojima (self condensing ball/ Earth/ Earth Jewel). They tie the life powers such as moving and falling called "AME-NO-TAKEMUSU-NO-BU" with the work of carrying on life. These are the Kami of Kamunagara who activate living movements and operations and prepare other powers that rotate around the Sun to unify all forever..relating to the line" Kami-no-tsudoe ni tsudoe" which refers directly to the operations of weaving together the Uchiki and Sotoki (Yin and Yang).

Current Doshu (Moriteru Doshu) is a board member of Tsubaki Grand Shrine in Japan which is the #1 shrine among the 2000 or so shrines to SARUTAHIKONOOKAMI. This Kami was enshrined at Aiki Jinja in Iwama as lead Kami by Yamamoto Yukiyasu Guji who was the 96th Gneration Guji (High Priest) of Tsubaki Grand SHrine and was the man who taught O'Sensei re: Triangle/Circle/Square. SARITAHIKONOOKAMI and the Mitama of O'Sensei are also enshrined at Tsubaki Grand Shrine of America, the only Jinja Shinto Shrine in North America www.TsubakiShrine.org

I think so, in a manner of speaking:

This is the best book I have found on O'Sensai and aikido's spirituality. Warning: it is complicated and quite intense, but well worth the read if you are interested.
