Bhashya
अयं धर्मः— ‘अयम्’ इति अप्रत्यक्षोऽपि धर्मः कार्येणतथा दृष्टेनानुष्ठीयमानेन आचाररूपेण सत्याख्यो भवति, स एव धर्मः; सोऽपि द्विप्रकार एव सामान्यविशेषात्म- रूपेण- सामान्यरूपः पृथिव्यादिसमवेतः, विशेषरूपः कार्य- करणसंघातसमवेतः; तत्र पृथिव्यादिसमवेते वर्तमानक्रिया- रूपे सत्ये, तथा अध्यात्मं कार्यकरणसंघातसमवेते सत्ये, भवः सात्यः- 'सत्येन वायुगवाति' इति श्रुत्यन्तरात् ॥
In plain words
'This is dharma' — take the word 'this' seriously. Dharma itself can never be seen directly. What you see is its effect: conduct, actually carried out, visible in the world — and that visible practice is what earns the name 'truth.' That is dharma. And it comes in exactly two forms: a general form, living in earth and the other elements, and a particular form, living in your own body and its organs. Wherever that living activity shows up as truth — out there in the elements, or in here in your own body — what arises from it is called 'the truthful.' As another scripture puts it: 'by truth the wind blows.'
Close to the Sanskrit
'This dharma' — [as to the word] 'this': although dharma is not perceptible, still, through its effect — namely through conduct, seen and being performed — it becomes known by the name 'truth'; that alone is dharma. That too is of exactly two kinds, in the form of the general and the particular: the general form inheres in earth and the rest; the particular form inheres in the aggregate of body and organs. There, when the present activity inherent in earth and the rest is truth, and likewise, with reference to the self, when it is truth as inherent in the aggregate of body and organs, that which arises is 'sātya' — on the authority of another scriptural text, 'by truth the wind blows.'
