Verse 54

आत्मसत्तां त्यजन्नेतां चेत्यं भावयसि स्वयम् ।यदा राम तदा यासि चित्ततामतिदुःखदाम्

In plain words

When, O Rāma, abandoning this very existence that is ātman, you yourself conceive something as a mere object of thought -- then you go to the condition of citta, a condition that brings the utmost suffering.
