In Bhagavad-gītā (18.61) it is said:
hṛd-deśe ’rjuna tiṣṭhati
“The Supreme Lord is situated in everyone’s heart, O Arjuna, and is directing the wanderings of all living entities, who are seated as on a machine, made of material energy.” A material body is manufactured by the external energy according to the direction of the Supreme Personality of Godhead. The conditioned soul, being seated on this machine, wanders throughout the universe, and because of his bodily conception of life he only suffers. Actually the suffering of being blasphemed and the enjoyment of being praised, the acceptance of a good welcome or of chastisement by harsh words, are felt in the material conception of life; but since the body of the Supreme Personality of Godhead is not material but sac-cid-ānanda-vigraha, He is unaffected by insults or greetings, blasphemy or prayers. Being always unaffected and complete, He does not feel extra pleasure when offered nice prayers by the devotee, although the devotee benefits by offering prayers to the Lord. Indeed, the Lord is very kind to His so-called enemy because one who always thinks of the Personality of Godhead as an enemy also benefits, although he thinks of the Lord adversely. If a conditioned soul, thinking of the Lord as an enemy or a friend, somehow or other becomes attached to the Lord, he receives great benefit.
