Verse 21

संसक्तिर्द्विविधा प्रोक्ता वन्द्या वन्ध्या च राघव ।वन्ध्या सर्वत्र मूढानां वन्द्या तत्त्वविदां निजा

In plain words

Attachment, Rāghava, is declared to be of two kinds: vandyā, the reverend, and vandhyā, the barren. The barren kind belongs everywhere to the deluded; the reverend is the very own possession of those who know the truth.
