CC Madhya 6.157
tvayy ekā sarva-saṁśraye
tvayi no guṇa-varjite
hlādinī — the pleasure potency; sandhinī — the eternity potency; samvit — the knowledge potency; tvayi — in You; ekā — one spiritual (cit) potency; sarva-saṁśraye — the shelter of everything; hlāda — pleasure; tāpa-karī — causing displeasure; miśrā — mixed; tvayi — in You; na u — not; guṇa-varjite — devoid of all material qualities.
“ ‘The Supreme Personality of Godhead is sac-cid-ānanda-vigraha. This means that He originally has three potencies — the pleasure potency, the potency of eternality and the potency of knowledge. Together these are called the cit potency, and they are present in full in the Supreme Lord. For the living entities, who are part and parcel of the Lord, the pleasure potency in the material world is sometimes displeasing and sometimes mixed. This is not the case with the Supreme Personality of Godhead, because He is not under the influence of the material energy or its modes.’
