Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 3-4
Sanskrit:
नि:सृतं ते मुखाम्भोजाद् यदाह भगवानज: ।पुत्रेभ्यो भृगुमुख्येभ्यो देव्यै च भगवान् भव: ॥ ३ ॥एतद् वै सर्ववर्णानामाश्रमाणां च सम्मतम् ।श्रेयसामुत्तमं मन्ये स्त्रीशूद्राणां च मानद ॥ ४ ॥
ITRANS:
niḥsṛtaṁ te mukhāmbhojādyad āha bhagavān ajaḥputrebhyo bhṛgu-mukhyebhyodevyai ca bhagavān bhavaḥ
Translation:
O most magnanimous Lord, the instructions on this process of Deity worship first emanated from Your lotus mouth. Then they were spoken by the great Lord Brahmā to his sons, headed by Bhṛgu, and by Lord Śiva to his wife, Pārvatī. This process is accepted by and appropriate for all the occupational and spiritual orders of society. Therefore I consider worship of You in Your Deity form to be the most beneficial of all spiritual practices, even for women and śūdras.
