कर्मणा निर्मितो देहः प्रारब्धं तस्य कल्प्यताम् ।नानादेरात्मनो युक्तं नैवात्मा कर्मनिर्मितः ॥ ४५९ ॥
In plain words
The body is what karma built — so if prārabdha belongs anywhere, let it belong to the body. It makes no sense at all to pin it on the Self, which has no beginning. The Self was never something karma made in the first place.
Close to the Sanskrit
The body is made by karma; let prārabdha be attributed to it. It is not fitting [to attribute prārabdha] to the beginningless Self; the Self is never made by karma.
