अहिनिर्ल्वयनीजातः शुच्यादिर्नाहिमाप्नुयात् ।तथा स्थूलादिसंभूतः शुच्यादिर्नाप्नुयादिमम् ॥ १६ ॥
In plain words
What belongs to a snake's discarded skin does not touch the snake itself. In the same way, the changing conditions of the gross and subtle coverings do not touch the Self.
Close to the Sanskrit
Just as purity and similar conditions arising in a snake's cast skin would not affect the snake, so conditions arising in the gross body and the like do not affect this Self.
