Occult Practices of Certain Hindus Introduced in the States Are Completely Contrary to the Teachings and Should Be Avoided by the Friends

…indeed, such occult practices as certain Hindus have introduced in the States, and which some superficial and superstitious individuals have adopted and are trying, by all sorts of devices, to popularize, are absolutely foreign, nay positively opposed to the very spirit and letter of the Teachings, and the believers, therefore, should strictly and at all times avoid the company of such people, lest they may unconsciously and inevitably fall under their baneful influence and become gradually alienated from the Cause.

…The friends also should be warned not to indulge in such activities that draw their inspiration from Hindu occultist sources, as these do not only lead them away from the Cause, but can cause them considerable mental harm, and thus permanently injure their mind as well as their body.

(From a letter written on behalf of the Guardian to two believers, August 5, 1939)
