Śrīmad-Bhāgavatam
[Canto 9, Ch. 8]
sattva-guṇa, rajo-guṇa and tamo-guṇa, they can see only the actions and reactions of these three modes of material nature. Because of the actions and reactions of the mode of ignorance, whether the living entities are awake or sleeping, they can see only the workings of material nature; they cannot see Your Lordship.
PURPORT
Unless one is situated in the transcendental loving service of the Lord, one is unable to understand the Supreme Personality of Godhead. The Lord is situated in everyone's heart. However, because the conditioned souls are influenced by material nature, they can see only the actions and reactions of material nature, but not the Supreme Personality of Godhead. One therefore must purify himself internally and externally:
apavitraḥ pavitro vā sarvāvasthām gato 'pi vā yaḥ smaret puṇḍarīkākṣam sa bāhyābhyantaraḥ śuciḥ
To keep ourselves externally clean we should bathe three times daily, and for internal cleanliness we must cleanse the heart by chanting the Hare Kṛṣṇa  mantra . The members of the Kṛṣṇa consciousness movement must always follow this principle ( bāhyābhyantaraḥ śuciḥ ). Then it will one day be possible to see the Supreme Personality of Godhead face to face.
