glands, ductless

49:5.193. Spirit-re­cep­tion se­ries. There are three groups of mind de­sign as re­lated to con­tact with spirit af­fairs. This clas­si­fi­ca­tion does not re­fer to the one-, two-, and three-brained or­ders of mor­tals; it refers pri­mar­ily to gland chem­istry, more par­tic­u­larly to the or­ga­ni­za­tion of cer­tain glands com­pa­ra­ble to the pi­tu­itary bod­ies. The races on some worlds have one gland, on oth­ers two, as do Uran­tians, while on still other spheres the races have three of these unique bod­ies. The in­her­ent imag­i­na­tion and spir­i­tual re­cep­tiv­ity is def­i­nitely in­flu­enced by this dif­fer­en­tial chem­i­cal en­dow­ment.

49:5.20Of the spirit-re­cep­tion types, sixty-five per cent are of the sec­ond group, like the Uran­tia races. Twelve per cent are of the first type, nat­u­rally less re­cep­tive, while twenty-three per cent are more spir­i­tu­ally in­clined dur­ing ter­res­trial life. But such dis­tinc­tions do not sur­vive nat­u­ral death; all of these racial dif­fer­ences per­tain only to the life in the flesh.

65:6.6But many seem­ingly mys­te­ri­ous ad­just­ments of liv­ing or­gan­isms are purely chem­i­cal, wholly phys­i­cal. At any mo­ment of time, in the blood stream of any hu­man be­ing there ex­ists the pos­si­bil­ity of up­ward of 15,000,000 chem­i­cal re­ac­tions be­tween the hor­mone out­put of a dozen duct­less glands.
