दोषैरेतैः कुलघ्नानां वर्णसङ्करकारकैः

etaiḥ — these

By these wrongs of those who destroy a family — by the confusion of lineage they cause — the enduring duties of community and household are undone.

इन्द्रियाणि मनो बुद्धिरस्याधिष्ठानमुच्यते

etaiḥ — by these

etaiḥ — from this

A person freed from these three gates of darkness, son of Kunti, does what is good for the self, and so goes to the highest.
