Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 27
Sanskrit:
सात्त्विक्याध्यात्मिकी श्रद्धा कर्मश्रद्धा तु राजसी ।तामस्यधर्मे या श्रद्धा मत्सेवायां तु निर्गुणा ॥ २७ ॥
ITRANS:
sāttviky ādhyātmikī śraddhākarma-śraddhā tu rājasītāmasy adharme yā śraddhāmat-sevāyāṁ tu nirguṇā
Translation:
Faith directed toward spiritual life is in the mode of goodness, faith rooted in fruitive work is in the mode of passion, faith residing in irreligious activities is in the mode of ignorance, but faith in My devotional service is purely transcendental.
