25. And on account of both (i.e. the origin and the dissolution of the world) being directly declared (to have Brahman for their material cause).
This Sûtra supplies a further argument for Brahman's being the general material cause.—Brahman is the material cause of the world for that reason also that the origination as well as the dissolution of the world is directly spoken of in the sacred texts as having Brahman for their material cause, 'All these beings take their rise from the ether and return into the ether' (Ch. Up. I, 9, 1). That that from which some other thing springs and into which it returns is the material cause of that other thing is well known. Thus the earth, for instance, is the material cause of rice, barley, and the like.—The word 'directly' (in the Sûtra) notifies that there is no other material cause, but that all this sprang from the ether only.—Observation further teaches that effects are not re-absorbed into anything else but their material causes.
26. (Brahman is the material cause) on account of (the Self) making itself; (which is possible) owing to modification.
Brahman is the material cause for that reason also that Scripture—in the passage, 'That made itself its Self' (Taitt. Up. II, 7)—represents the Self as the object of action as well as the agent.—But how can the Self which as agent was in full existence previously to the action be made out to be at the same time that which is effected by the action?—Owing to modification, we reply. The Self, although in full existence previously to the action, modifies itself into something special, viz. the Self of the effect. Thus we see that causal substances, such as clay and the like, are, by undergoing the process of modification, changed into their products.—The word 'itself' in the passage quoted intimates the absence of any other operative cause but the Self.
The word 'parinâmât' (in the Sûtra) may also be taken as constituting a separate Sûtra by itself, the sense of which would be: Brahman is the material cause of the world for that reason also, that the sacred text speaks of Brahman and its modification into the Self of its effect as co-ordinated, viz. in the passage, 'It became sat and tyat, defined and undefined' (Taitt. Up. II, 6).
27. And because Brahman is called the source.
Brahman is the material cause for that reason also that it is spoken of in the sacred texts as the source (yoni); compare, for instance, 'The maker, the Lord, the person who has his source in Brahman' (Mu. Up. III, 1, 3); and 'That which the wise regard as the source of all beings' (Mu. Up. I, 1, 6). For that the word 'source' denotes the material cause is well known from the use of ordinary language; the earth, for instance, is called the yoni of trees and herbs. In some places indeed the word yoni means not source, but merely place; so, for instance, in the mantra, 'A yoni, O Indra, was made for you to sit down upon' (Rik. Samh. I, 104, 1). But that in the passage quoted it means 'source' follows from a complementary passage, 'As the spider sends forth and draws in its threads,' &c.—It is thus proved that Brahman is the material cause of the world.—Of the objection, finally, that in ordinary life the activity of operative causal agents only, such as potters and the like, is preceded by reflection, we dispose by the remark that, as the matter in hand is not one which can be known through inferential reasoning, ordinary experience cannot be used to settle it. For the knowledge of that matter we rather depend on Scripture altogether, and hence Scripture only has to be appealed to. And that Scripture teaches that the Lord who reflects before creation is at the same time the material cause, we have already explained. The subject will, moreover, be discussed more fully later on.
28. Hereby all (the doctrines concerning the origin of the world which are opposed to the Vedânta) are explained, are explained.
The doctrine according to which the pradhâna is the cause of the world has, in the Sûtras beginning with I, 1, 5, been again and again brought forward and refuted. The chief reason for the special attention given to that doctrine is that the Vedânta-texts contain some passages which, to people deficient in mental penetration, may appear to contain inferential marks pointing to it. The doctrine, moreover, stands somewhat near to the Vedânta doctrine since, like the latter, it admits the non-difference of cause and effect, and it, moreover, has been accepted by some of the authors of the Dharma-sûtras, such as Devala, and so on. For all these reasons we have taken special trouble to refute the pradhâna doctrine, without paying much attention to the atomic and other theories. These latter theories, however, must likewise be refuted, as they also are opposed to the doctrine of Brahman being the general cause, and as slow-minded people might think that they also are referred to in some Vedic passages. Hence the Sûtrakâra formally extends, in the above Sûtra, the refutation already accomplished of the pradhâna doctrine to all similar doctrines which need not be demolished in detail after their great protagonist, the pradhâna doctrine, has been so completely disposed of. They also are, firstly, not founded on any scriptural authority; and are, secondly, directly contradicted by various Vedic passages.—The repetition of the phrase 'are explained' is meant to intimate that the end of the adhyâya has been reached.
