Sukham, pleasure or happiness, should always be in that which is favorable for the cultivation of the spiritual knowledge of Kṛṣṇa consciousness. And similarly, that which is painful or which causes distress is that which is unfavorable for the cultivation of Kṛṣṇa consciousness. Anything favorable for the development of Kṛṣṇa consciousness should be accepted, and anything unfavorable should be rejected.
-Bhagavad-Gita Chapter 10 Verse 4-5, Purport

आपन्न: संसृतिं घोरां यन्नाम विवशो गृणन् ।
तत: सद्यो विमुच्येत यद्ब‍िभेति स्वयं भयम् ॥ १४ ॥
Living beings who are entangled in the complicated meshes of birth and death can be freed immediately by even unconsciously chanting the holy name of Kṛṣṇa, which is feared by fear personified.
-ŚB 1.1.14
