Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 21
अहं सर्वेषु भूतेषु भूतात्मावस्थित: सदा ।तमवज्ञाय मां मर्त्य: कुरुतेऽर्चाविडम्बनम् ॥ २१ ॥
ahaṁ sarveṣu bhūteṣubhūtātmāvasthitaḥ sadātam avajñāya māṁ martyaḥkurute ’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.
In purified consciousness, or Kṛṣṇa consciousness, one sees the presence of Kṛṣṇa everywhere. Therefore if one only engages in Deity worship in the temple and does not consider other living entities, then he is in the lowest grade of devotional service. One who worships the Deity in the temple and does not show respect to others is a devotee on the material platform, in the lowest stage of devotional service. A devotee should try to understand everything in relationship with Kṛṣṇa and try to serve everything in that spirit. To serve everything means to engage everything in the service of Kṛṣṇa. If a person is innocent and does not know his relationship with Kṛṣṇa, an advanced devotee should try to engage him in the service of Kṛṣṇa. One who is advanced in Kṛṣṇa consciousness can engage not only the living being but everything in the service of Kṛṣṇa.
