SB Canto 7

My dear father, please give up your demoniac mentality. Do not discriminate in your heart between enemies and friends; make your mind equipoised toward everyone. Except for the uncontrolled and misguided mind, there is no enemy within this world.

SB 7.8.9, Translation and Purport: Prahlāda Mahārāja continued: My dear father, please give up your demoniac mentality. Do not discriminate in your heart between enemies and friends; make your mind equipoised toward everyone. Except for the uncontrolled and misguided mind, there is no enemy within this world. When one sees everyone on the platform of equality, one then comes to the position of worshiping the Lord perfectly.

Unless one is able to fix the mind at the lotus feet of the Lord, the mind is impossible to control. As Arjuna says in :Bhagavad-gītā (6.34):

cañcalaṁ hi manaḥ kṛṣṇa

pramāthi balavad dṛḍham

tasyāhaṁ nigrahaṁ manye

vāyor iva suduṣkaram

"For the mind is restless, turbulent, obstinate and very strong, O Kṛṣṇa, and to subdue it, it seems to me, is more difficult than controlling the wind." The only bona fide process for controlling the mind is to fix the mind by service to the Lord. We create enemies and friends according to the dictation of the mind, but actually there are no enemies and friends. paṇḍitāḥ sama-darśinaḥ [Bg. 5.18]. Samaḥ sarveṣu bhūteṣu mad-bhaktiṁ labhate parām [Bg. 18.54]. To understand this is the preliminary condition for entering into the kingdom of devotional service.
