Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 37

Sanskrit:

शारीरा मानसा दिव्या वैयासे ये च मानुषा: ।भौतिकाश्च कथं क्लेशा बाधन्ते हरिसंश्रयम् ॥ ३७ ॥

ITRANS:

śārīrā mānasā divyāvaiyāse ye ca mānuṣāḥbhautikāś ca kathaṁ kleśābādhante hari-saṁśrayam

Translation:

Therefore, O Vidura, how can persons completely under the shelter of Lord Kṛṣṇa in devotional service be put into miseries pertaining to the body, the mind, nature, and other men and living creatures?

Purport:

Every living entity within this material world is always afflicted by some kind of miseries, pertaining either to the body, the mind or natural disturbances. Distresses due to cold in winter and severe heat in summer always inflict miseries on the living entities in this material world, but one who has completely taken shelter of the lotus feet of the Lord in Kṛṣṇa consciousness is in the transcendental stage; he is not disturbed by any miseries, either due to the body, the mind or natural disturbances of summer and winter. He is transcendental to all these miseries.
