Welcome to TNSA
The National Spiritual Alliance is located in Lake Pleasant, Massachusetts, the oldest continuously existing same-site Spiritualist community in the United States, with roots reaching back to the 1870s. Founded in 1913 by Spiritualist minister and publisher G. Tabor Thompson, TNSA continues to carry forward this living tradition. Our home, the beautiful and historic Thompson Temple, remains a gathering place for spirit communication, healing, and fellowship at the heart of Lake Pleasant’s enduring Spiritualist heritage.
The 7 Principles of
The National Spiritual Alliance
PRINCIPLE 1. INFINITE INTELLIGENCE: Infinite Intelligence is Deity, the designing and creating energy for all that exists. Existence is essence, guidance, meaning, purpose.
]PRINCIPLE 2. ONE UNIVERSE/MANY DIMENSIONS: From one source came all. No matter surface differences, all is within us and each of us is within all else.
PRINCIPLE 3. THE IMMORTAL SOUL: The soul is eternal. While the body dies, the spirit lives on.
PRINCIPLE 4. COMMUNICATION BETWEEN MATERIALITY AND NON-MATERIALITY: Spirit transcends dimension. All souls, flesh and spirit, communicate with each other.
PRINCIPLE 5. PURSUIT OF TRUTH: Truth is eternal. We seek truth within ourselves, from other souls, sacred writings, and the natural order which sustains us.
PRINCIPLE 6. PERSONAL RESPONSIBILITY: Cause produces effect through thoughts, words, and deeds. We create ourselves and our circumstances and are alone responsible for our choices and creations.
PRINCIPLE 7. AFFILIATION AND MEMBERSHIP: Patience is the path to tolerance and tolerance is the path to love. We associate with this alliance to lovingly cooperate with ALL who seek spiritual understanding.
