Śrīmad-Bhāgavatam · Text 3.29.21
Who is speaking and story frame
अहं सर्वेषु भूतेषु भूतात्मावस्थित: सदा ।
तमवज्ञाय मां मर्त्य: कुरुतेऽर्चाविडम्बनम् ॥ २१ ॥
ahaṁ sarveṣu bhūteṣu
bhūtātmāvasthitaḥ sadā
tam avajñāya māṁ martyaḥ
kurute ’rcā-viḍambanam
I am present in every living entity as the Supersoul. If someone neglects or disregards that Supersoul everywhere and engages himself in the worship of the Deity in the temple, that is simply imitation.
