We shall now take notice of the other meanings which the lexicons assign to _sat_, beside the being and entity of God परमार्थ सत्व we have so long dwelt upon. It means the goodness and excellence of a thing. साधुत्वप्रशस्तादिभिः सच्छब्दोऽपि । वाचस्पत्याभिदानं ॥ In this sense the phrase _Om tat sat_ would mean “God The Good”, which is quite correct on all hands. In English the etymology of God is good, and so the Sanskrit _sat_ means both God and good; thus also all systems of philosophy predicate the attribute of goodness of the nature of God. The Persian term _Khoda_ though so nearly allied to God and _sat_ in sound, will be found to bear no affinity with either; but to owe its derivation to the Sanskrit स्वदा (from स्वदत्तः) meaning self-produced; _swa_ स्व being invariably rendered into _kha_ in Persian, as _swata_ स्वत _khod_, _swasri_ स्वसृ khwahir &c. [Sidenote: 8. Another sense of _Sat_.] _Sat_ appears moreover in the sense of sitting in composition with an objective word preceding it, as _diri-shad_ a celestial, _sabhásat_ a courtier. It is from the root _sad_, Latin _sedo_—to sit, with the suffix _kwip_. Thus we have in the Kathá Vallí: (V. 2.) हंसः शुचिसद्वसुरन्तरीक्षः । सद्धेता वेदिषदतिथिर्द्दूरोन सत् । नृषद्वरसदृतसद्व्योमसद् । सद् अब्जा गोजा ऋतजा अद्रिजाऋतं बृहत् ।५ ।२ । “The Hansa, (God) sits above the heavens, it dwells in the atmosphere, as invokers it dwells in temples, and as guests it is not afar from us. It dwells in man, in truth, in the ether, in water, mountains &c. &c.” XVII. THE CONCLUSIVE LESSON ON THE PRACTICE OF YOGA. After our long and lengthy discussion on the subject of Yoga, and the sacred and mysterious words wherewith it is conducted, our treatise will be deemed incomplete until we set a form or praxis of the manner in which it is to be conducted; and particularly by those who are fully persuaded of its efficacy, and prepared for its practice, but are prevented from it for want of proper guides to initiate them into it, or deterred by the arduousness of the rites imposed upon them by false Yogis, as to give up the exercise in disgust and hopelessness of their possibility ever to master it.
