Śrīmad-Bhāgavatam · Text 6.4.13
Who is speaking and story frame
अन्तर्देहेषु भूतानामात्मास्ते हरिरीश्वर: ।
सर्वं तद्धिष्ण्यमीक्षध्वमेवं वस्तोषितो ह्यसौ ॥ १३ ॥
antar deheṣu bhūtānām
ātmāste harir īśvaraḥ
sarvaṁ tad-dhiṣṇyam īkṣadhvam
evaṁ vas toṣito hy asau
The Supreme Personality of Godhead is situated as the Supersoul within the cores of the hearts of all living entities, whether moving or nonmoving, including men, birds, animals, trees and, indeed, all living entities. Therefore you should consider every body a residence or temple of the Lord. By such vision you will satisfy the Lord. You should not angrily kill these living entities in the forms of trees.
