Shloka 2.20.48
अयोध्याकाण्डे विंशः सर्गः — Rama Enters Kauśalyā’s Antaḥpura; Ritual Preparations and the Shock of Exile
उपवासैश्च योगैश्च बहुभिश्च परिश्रमैः।दुःखं संवर्धितो मोघं त्वं हि दुर्गतया मया।।।।
upavāsaiś ca yogaiś ca bahubhiś ca pariśramaiḥ | duḥkhaṃ saṃvardhito moghaṃ tvaṃ hi durgatayā mayā ||
With fasts, with disciplines of yoga, and with many hardships, I raised you with difficulty—yet now, alas, it seems all has come to nothing, for I am utterly unfortunate.
Through meditation, through fasts and with a great deal of efforts you have been brought up by this luckless (mother). But alas! this is all in vain.
It reflects the tension between personal sacrifice and outcomes; Dharma values the intention and purity of effort even when results appear bitter.
Kausalyā recalls her religious observances and hardships undertaken for Rāma, lamenting that the present calamity makes those efforts feel futile.
Self-sacrifice—her life of restraint and effort is presented as dedicated to her child’s welfare.
