Ramayana 2.64.75

अयमात्मभवश्शोको मामनाथमचेतनम्।संसादयति वेगेन यथा कूलं नदीरयः।।।।

ayam ātmabhavaḥ śoko mām anātham acetanaṃ | saṃsādayati vegena yathā kūlaṃ nadīrayaḥ ||

This grief, born from myself, is swiftly wearing me down—like a river’s current rapidly erodes its bank—leaving me helpless and insensible.
