Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 43
Sanskrit:
तत् सर्वव्यापकं चित्तमाकृष्यैकत्र धारयेत् ।नान्यानि चिन्तयेद् भूय: सुस्मितं भावयेन्मुखम् ॥ ४३ ॥
ITRANS:
tat sarva-vyāpakaṁ cittamākṛṣyaikatra dhārayetnānyāni cintayed bhūyaḥsu-smitaṁ bhāvayen mukham
Translation:
One should then pull the consciousness back from all the limbs of that transcendental body. At that time, one should meditate only on the wonderfully smiling face of the Lord.
