Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 48

Sanskrit:

तं दुर्जयं शत्रुमसह्यवेग-मरुन्तुदं तन्न विजित्य केचित् ।कुर्वन्त्यसद्विग्रहमत्र मर्त्यै-र्मित्राण्युदासीनरिपून् विमूढा: ॥ ४८ ॥

ITRANS:

tam durjayaṁ śatrum asahya-vegamarun-tudaṁ tan na vijitya kecitkurvanty asad-vigraham atra martyairmitrāṇy udāsīna-ripūn vimūḍhāḥ

Translation:

Failing to conquer this irrepressible enemy, the mind, whose urges are intolerable and who torments the heart, many people are completely bewildered and create useless quarrel with others. Thus they conclude that other people are either their friends, their enemies or parties indifferent to them.

Purport:

Falsely identifying oneself as the material body, and accepting bodily expansions such as children and grandchildren to be one’s eternal property, one completely forgets that every living being is qualitatively one with God. There is no essential difference between one individual being and another, since all are eternal expansions of the Supreme Lord. The mind absorbed in false ego creates the material body, and by identification with the body, the conditioned soul is overwhelmed by false pride and ignorance, as described here.
