no expiation for the ungrateful

ब्रह्मघ्ने च सुरापे च चोरे भग्नव्रते तथा।
निष्कृतिर्विहिता सद्भिः कृतघ्ने नास्ति निस्कृतिः॥
brahmaghne ca surāpe ca core bhagnavrate tathā|
niṣkṛtirvihitā sadbhiḥ kṛtaghne nāsti niskṛtiḥ||

श्रीमद्वात्मीकिरामायणं किष्किन्धाकाण्डं   ३४----१२
śrīmadvātmīkirāmāyaṇaṁ kiṣkindhākāṇḍaṁ   34----12

The learned sages have prescribed suitable expiation for the grave sins like murdering of a learned man, consuming  hooch, burglary or  breaking of holy vows.  But no expiation is prescribed for the sin of being ungrateful.

let all my relatives abandon me, let the great people insult me, still I am in supreme bliss since my life  is GOVINDA alone.
