Śrīmad-Bhāgavatam · Text 10.8.35
Who is speaking and story frame
नाहं भक्षितवानम्ब सर्वे मिथ्याभिशंसिन: ।
यदि सत्यगिरस्तर्हि समक्षं पश्य मे मुखम् ॥ ३५ ॥
nāhaṁ bhakṣitavān amba
sarve mithyābhiśaṁsinaḥ
yadi satya-giras tarhi
samakṣaṁ paśya me mukham
Lord Śrī Kṛṣṇa replied: My dear mother, I have never eaten dirt. All My friends complaining against Me are liars. If you think they are being truthful, you can directly look into My mouth and examine it.
