Now the Adepts have for ages pursued scientific experimentation and investigation upon those lines. Seers themselves of the highest order, they have recorded not only their own actual experiences beyond the veil of matter, on both sides, but have collected, compared, analyzed and preserved the records of experiences of the same sort by hundreds of thousands of lesser seers, their own disciples; and this process has been going on from time immemorial. Let Science laugh as it may, the Adepts are the only true scientists, for they take into account every factor in the question, whereas Science is limited by brain-power, by circumstance, by imperfection of instruments, and by a total inability to perceive anything deeper than the mere phenomena presented by matter. The records of the visions and experiences of the greater and lesser seers, through the ages, are extant to-day. Of their mass, nothing has been accepted except that which has been checked and verified by millions of independent observations; and therefore the Adepts stand in the position of those who possess actual experimental knowledge of what precedes the birth of the Ego in a human form, and what succeeds when the "mortal coil" is cast away. This recording of experiences still goes on; for the infinity of the changes of Nature in its evolution permits of no stoppage, no "last word," no final declaration. As the earth sweeps around the sun, it not only passes through new places in its orbit, but, dragged as it is by the sun through his greater orbit, involving millions of millions of years, it must in that larger circle enter upon new fields in space and unprecedented conditions. Hence the Adepts go farther yet and state that, as the phenomena presented by matter to-day are different from those presented a million years ago, so matter will in another million of years show different phenomena still. Indeed, if we could translate our sight to that time, far back in the past of our globe, we could see conditions and phenomena of the material world so different from those now surrounding us that it would be almost impossible to believe we had ever been in such a state as that then prevailing. And the changes toward the conditions that will prevail at a point equally remote in advance of us, in time, and which will be not less than those that have occurred, are in progress now. Nothing in the material world endures absolutely unchanged in itself or its conditions, even for the smallest conceivable portion of time. All that _is_, is forever in process of _becoming_ something else. This is not mere transcendentalism, but is an old established doctrine called, in the East, "the doctrine of the constant, eternal change of atoms from one state into another." V.
