The soul being a self moved monad, is one, whether it connects itself with two or with three; in other words the essence remains the same whatever its manifestations may be. The one soul may have two aspects, Intelligence and Passion, as in brutes; or it may have three aspects, as in man &c. For more of this see Lewes’ History of Philosophy (Vol. I p. 33 and p. 34). [Sidenote: 6. Query concerning Nature Worship.] There rises another question of some importance in this place as, what has the Yogi or worshipper of God to do with the objects presented to him in the different groups under the partitions of _Om_, when his business is solely to meditate on the nature and attributes of the Deity? [Sidenote: 7. Spiritual Worship.] To this it may be answered that, the Hindu Yogi or meditative sage is enjoined to meditate on the Supreme Spirit in Spirit, “_átmá átmanyeva chintayet_”. (आत्मा आत्मन्येबचिन्तयेत्). He does not adore any visible object, but contemplates his creator with all his attributes as displayed in creation, which he sums up abstractedly in his own spirit and mind. There can be no contemplation of the inscrutable and incomprehensible nature of God apart from the light we derive from the abstract meditation of all sensible and intellectual natures. “Observe every thing in thyself and so shalt thou behold the Supreme.” सर्ब्बमात्मगतं पश्यतेनात्मानं परिपश्यसि । [Sidenote: 8. Self knowledge. What?] The old rule of self knowledge आत्मतत्त्व or know thyself आत्मानं जानीहि, which was believed to constitute highest wisdom, and which has given rise to different interpretations in various schools of philosophy, does not mean the knowledge of one’s state and nature to be sufficient for him; but that of his soul which makes him truly great. The wise Socrates looked inwards, and there discovered the moral and psychological truths the world has derived from him. His pupil the divine Plato looked within him, and there found the eternal ideas of which sense awakened reminiscence. [Sidenote: 9. Knowledge of the Soul.] The Hindu Yogi too looks inward and views within the circle of his cranium symbolized as _Om_, his soul seated as a ray and figure of the Divinity, and encompassed by the abstract ideas of all things whose impressions he has received by sense and mind. He then learns to distinguish by his discriminative power called the _átmánátma viveka_, (आत्मानात्मविवेक) the soul of the Universe from all the representations which it presents to his mind. [Sidenote: 10. Of one in Many.] The Platonic system had also a sort of classification in which the search for One in Many and Many in One, together with the detection of the One in the Many was the constant aim, consult for further information on this head in Lewes’ History of Philosophy. (Vol. 1. p. 237 and p. 405). XV. THE UNITARIAN FORMULA ॐ तत् सत् ONE THAT IS. [Sidenote: 1. Om the one.]
