kṛṣṇa-bhakta — niṣkāma, ataeva ‘śānta’
bhukti-mukti-siddhi-kāmī — sakali ‘aśānta’

(Cc. Madhya-līlā 19.149)

Only kṛṣṇa-bhakta, a devotee of Krishna is peaceful. He has no other desire - no desire for material enjoyment, no desire for liberation, merging in Brahman. Do you understand? No desire. Only he is peaceful. Karmī, jñānīs, yogīs, they has desires. Karmī has desire for material enjoyment , jñānīs has desire for liberation, merging into Brahman of the Lord, yogī has desire for yogic perfection, mystic perfection. So they are all always disgusted. They have no peace at all. Only a kṛṣṇa-bhakta, who has developed unalloyed devotion unto Krishna, is peaceful, always happy, cheerful, blissful, peaceful. Yes. Do you understand?

karmī-jñānī-yogi sakali kṛṣṇa-bahir-mukha
kabe naya āsvādaye kṛṣṇa-sevā-sukha

Karmīs, jñānīs, yogīs, all are conditioned souls. They have not developed attraction towards Krishna. They are all forgetful of Krishna. Kabe naya āsvādaye kṛṣṇa-sevā-sukha. They cannot taste what pleasure is there in keeping oneself engaged in Krishna’s loving service. They cannot taste it; they cannot have it.
