People are being healed by means of my instructions, both in and out of class. Many students, who have passed through a regular course of instruction from me, have been invalids and were healed in the class; but experience has shown that this defrauds the scholar, though it heals the sick. It is seldom that a student, if healed in a class, has left it understanding sufficiently the Science of healing to immediately enter upon its practice. Why? Because the glad surprise of suddenly regained health is a shock to the mind; and this holds and satisfies the thought with exuberant joy. This renders the mind less inquisitive, plastic, and tractable; and deep systematic thinking is impracticable until this impulse subsides. This was the principal reason for advising diseased people not to enter a class. Few were taken besides invalids for students, until there were enough practitioners to fill in the best possible manner the department of healing. Teaching and healing should have separate departments, and these should be fortified on all sides with suitable and thorough guardianship and grace. Only a very limited number of students can advantageously enter a class, grapple with this subject, and well assimilate what has been taught them. It is impossible to teach thorough Christian Science to promiscuous and large assemblies, or to persons who cannot be addressed individually, so that the mind of the pupil may be dissected more critically than the body of a subject laid bare for anatomical examination. Public lectures cannot be such lessons in Christian Science as are required to empty and to fill anew the individual mind. If publicity and material control are the motives for teaching, then public lectures can take the place of private lessons; but the former can never give a thorough knowledge of Christian Science, and a Christian Scientist will never undertake to fit students for practice by such means. Lectures in public are needed, but they must be subordinate to thorough class instruction in any branch of education. None with an imperfect sense of the spiritual signification of the Bible, and its scientific relation to Mind-healing, should attempt overmuch in their translation of the Scriptures into the "new tongue;" but I see that some novices, in the truth of Science, and some impostors are committing this error. _Is there more than one school of scientific healing?_ In reality there is, and can be, but one school of the Science of Mind-healing. Any departure from Science is an irreparable loss of Science. Whatever is said and written correctly on this Science originates from the Principle and practice laid down in Science and Health, a work which I published in 1875. This was the first book, recorded in history, which elucidates a pathological Science purely mental.
