Nor is this fact peculiar to the Vedic religion, but is, on the contrary, quite general. In every cult there are practices which act by themselves, by a virtue which is their own, without the intervention of any god between the individual who practises the rite and the end sought after. When, in the so-called Feast of the Tabernacles, the Jew set the air in motion by shaking willow branches in a certain rhythm, it was to cause the wind to rise and the rain to fall; and it was believed that the desired phenomenon would result automatically from the rite, provided it were correctly performed.[64] This is the explanation of the fundamental importance laid by nearly all cults upon the material portion of the ceremonies. This religious formalism--very probably the first form of legal formalism--comes from the fact that since the formula to be pronounced and the movements to be made contain within themselves the source of their efficacy, they would lose it if they did not conform absolutely to the type consecrated by success.
Thus there are rites without gods, and even rites from which gods are derived. All religious powers do not emanate from divine personalities, and there are relations of cult which have other objects than uniting man to a deity. Religion is more than the idea of gods or spirits, and consequently cannot be defined exclusively in relation to these latter.
These definitions set aside, let us set ourselves before the problem.
First of all, let us remark that in all these formulæ it is the nature of religion as a whole that they seek to express. They proceed as if it were a sort of indivisible entity, while, as a matter of fact, it is made up of parts; it is a more or less complex system of myths, dogmas, rites and ceremonies. Now a whole cannot be defined except in relation to its parts. It will be more methodical, then, to try to characterize the various elementary phenomena of which all religions are made up, before we attack the system produced by their union. This method is imposed still more forcibly by the fact that there are religious phenomena which belong to no determined religion. Such are those phenomena which constitute the matter of folk-lore. In general, they are the debris of passed religions, inorganized survivals; but there are some which have been formed spontaneously under the influence of local causes. In our European countries Christianity has forced itself to absorb and assimilate them; it has given them a Christian colouring. Nevertheless, there are many which have persisted up until a recent date, or which still exist with a relative autonomy: celebrations of May Day, the summer solstice or the carnival, beliefs relative to genii, local demons, etc., are cases in point. If the religious character of these facts is now diminishing, their religious importance is nevertheless so great that they have enabled Mannhardt and his school to revive the science of religions. A definition which did not take account of them would not cover all that is religious.
