A manual of mental science

Leander Edmund Whipple’s manual is a practical guide to the powers of mind, instruction in concentration, and the shaping of health and circumstance through mental discipline. It belongs to the New Thought tradition of self-help spirituality, and readers will find brief lessons aimed at training thought, will, and emotional control.

Leander Edmund Whipple is an obscure figure associated with occult and esoteric publishing. He appears chiefly as an author in the wider field of metaphysical or speculative literature, but little securely established biographical information is readily available.
