Śrīmad-Bhāgavatam · Text 3.24.40
Who is speaking and story frame
मात्र आध्यात्मिकीं विद्यां शमनीं सर्वकर्मणाम् ।
वितरिष्ये यया चासौ भयं चातितरिष्यति ॥ ४० ॥
mātra ādhyātmikīṁ vidyāṁ
śamanīṁ sarva-karmaṇām
vitariṣye yayā cāsau
bhayaṁ cātitariṣyati
I shall also describe this sublime knowledge, which is the door to spiritual life, to My mother, so that she also can attain perfection and self-realization, ending all reactions to fruitive activities. Thus she also will be freed from all material fear.
