"The soul is a special form of life, as the flame is a special form of motion." It is also a product of life, and life is the arrangement and re-arrangement of matter, subject to form, with which are associated the qualities of matter and the relations and interactions of these qualities.
"Gotama," Dr. Paul Carus remarks, "strange to say, anticipated the modern conception of the soul as it is now taught by the most advanced scientists of Europe." St. Paul, too, may be reckoned as one who, if he had lived in these days, would have given his support to that positive philosophy which regards the soul as a product of materiality; for, he says: "Howbeit that was not first which was spiritual, but that which was natural, and afterwards that which is spiritual. The first man is of the earth earthy; the second man (the soul) is the Lord from heaven."
When the distinction between the expressions "materiality" and "reality" is clearly discerned, it removes a difficulty out of our way when we come to consider a means of bringing into harmony the Christian and Buddhist conception of "soul." It has been contended that, if you deny substance to the soul, it is tantamount to asserting the non-existence of the soul. But if it is admitted that "reality" has existence as well as "materiality," this objection falls to the ground.
The definition of matter as that which occupies space is not a comprehensive one. It is only the definition of a supposed quality of matter; it is abstracted in our minds from other qualities. Therefore, if we regard "soul," more especially in its sublimated condition, as something akin to a quality of matter after matter, as we perceive it, has been abstracted, we have a residuum which both Christians and Buddhists alike can accept as an approximate explanation of the nature of "soul."
The eschatology of the soul, as indicated in the two systems, is less easy to harmonize. The soul, according to Catholic notions, after the death of the body, undergoes a purgatorial process; and, in the general view of Protestants, awaits—sleeping or waking—in the ante-room of a judgment-hall until a final verdict is pronounced on the Day of Doom; and then, and not till then, is it allotted its ultimate rest or unrest.
On the other hand, that which is in Buddhistic thought the counterpart of this soul, whether we call it a "group of ideas" or the "effects of Karma," must submit, till absolutely bereft of the formative faculty or desire to live, to continuous incarnations. This, however, does not involve a process of transmigration, as is sometimes incorrectly assumed.
Several illustrations have been made use of to explain the migrationless nature of the process. "When a lamp is lit at a burning lamp there is a kindling of the wick, but no transmigration of the flame." A thought is conveyed by words from one to another, but of the thought itself there is no migration. Neither is there migration of any part of an object to a photographic plate, nor in the reflection of an object in a mirror.
It is matter for speculation whether the Christian idea of tarriance in an ante-room, and more especially the purgatorial process, might not be strained in meaning so as to imply that re-incarnation on this planet is the fate of some souls, prior to their ultimate reception into Paradise or condemnation to everlasting fire. Some such idea, maybe, was afloat in the lifetime of Jesus, when the question was asked: "Is this Elias come again?"
The Christian and Buddhist conception of "soul" differs considerably as to position. The one stands isolated; the other is not so posited. The soul, according to the Buddhist, is not a "self-in-itself." "Buddhism does not deny the existence of a soul or individuality, but denies the independent existence of a soul or individuality." The Christian conception of the soul corresponds with that of Kapila, the founder of the Sankhya philosophy, in so far as he conceived the soul to be a kind of transcendent, sublimated body, the thinker of our thoughts and the doer of our acts. This dualism was rejected by Gotama.
It is necessary to bear in mind, with a view to the proper comprehension of Buddhist teaching in regard to the immortality of the soul, that, "although the Samskâras, or soul-forms, constituting our existence, come to an end as activities in the case of the saint who has extinguished desire, there remains an immortal residuum in the unconditioned elements of soul-form which are beyond the reach of death." After death such a saint might be said to have a continued existence (as others have) in the effects shed upon others by his Karma during his lifetime. The difference, as I understand it, is this: that, in the case of the saint, the formative element of Karma, as it has taken shape in bodily existence, ceases to be from the date of his sainthood; and subsequently the effects of Karma, which must continue to be shed on others as impressions as long as he lives, are informative—that is, do not carry with them a desire to live; and, consequently, the saint, from the date of his sainthood, may be said to have no continuing existence in the life of another sentient being.
