There are innumerable living entities throughout the material and spiritual universes, but still Lord Kṛṣṇa is full in Himself. To think that God has lost His personality because His many parts and parcels are distributed all over the universe is an illusion. That is a material calculation. Such calculations are possible only under the influence of the material energy, māyā.
-Chaitanya Charitamrit Adi 3.71, Translation and Purport

अच्छेद्योऽयमदाह्योऽयमक्ल‍ेद्योऽशोष्य एव च ।
नित्यः सर्वगतः स्थाणुरचलोऽयं सनातनः ॥ २४ ॥
This individual soul is unbreakable and insoluble, and can be neither burned nor dried. He is everlasting, present everywhere, unchangeable, immovable and eternally the same.
-BG 2.24
