Shankara Bhashya (commentary)
Moreover, the disputant1 who says that the effect is produced from an unborn cause, cannot furnish an illustration to support his view. In other words, it is consequently established that nothing is born from an unborn cause as there is no illustration to support this view. If,2 on the other hand, it be contended that the effect is born from a born cause, then that cause must be born from some other born cause and so on, which position never enables us to reach a cause which is, in itself, unborn. In other words, we are faced with an infinite regress.
Anandagiri Tika (glossary)
1 Disputant—The follower of the Sāṃkhya system contends that such effects as Mahat, etc., are evolved from the unborn Pradhāna, the cause being non-different from the effect. The Kārikā disproves this theory of the Sāṃkhyas as well as the creation theory of some Vedāntists. This theory is a matter of inference. But there is no illustration to draw the inference.
2 If, etc.—If the effect be produced from a born cause (i.e., a cause which is the effect of some other cause), then there will be an endless regress and we shall never arrive at a cause which is, itself, unborn.
