Śrīmad-Bhāgavatam
[Canto 7, Ch. 9]
nija-māyayā —by Your own external energy;  idam —this;  nānā iva —like many varieties;  taiḥ —by them (the modes);  avasitaḥ —experienced;  tat —that;  anupraviṣṭaḥ —entering into.
TRANSLATION
My dear Lord, You alone manifest Yourself as the entire cosmic manifestation, for You existed before the creation, You exist after the annihilation, and You are the maintainer between the beginning and the end. All this is done by Your external energy through actions and reactions of the three modes of material nature. Therefore whatever exists—externally and internally—is You alone.
PURPORT
As stated in the  Brahma-saṁhitā  (5.35):
eko 'py asau racayituṁ jagad-aṇḍa-koṭiṁ 
    yac-chaktir asti jagad-aṇḍa-cayā yad-antaḥ 
    aṇḍāntara-stha-paramāṇu-cayāntara-sthaṁ 
    govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
“I worship the Personality of Godhead, Govinda, who, by one of His plenary portions, enters the existence of every universe and every atomic particle and thus unlimitedly manifests His infinite energy all over the material creation.” To create this cosmic manifestation, Govinda, the Supreme Personality of Godhead, expands His external energy and thus enters everything in the universe, including the atomic particles. In this way He exists in the entire cosmic manifestation. Therefore the activities of the Supreme Personality of Godhead in maintaining His devotees are transcendental, not material. He exists in everything as the cause and effect, yet He is separate, existing beyond this cosmic manifestation. This is also confirmed in  Bhagavad-gītā  (9.4):
mayā tatam idaṁ sarvaṁ 
    jagad avyakta-mūrtinā 
    mat-sthāni sarva-bhūtāni 
    na cāhaṁ teṣv avasthitaḥ
