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

धर्म: प्रोज्झितकैतवोऽत्र परमो निर्मत्सराणां सतां
वेद्यं वास्तवमत्र वस्तु शिवदं तापत्रयोन्मूलनम् ।
श्रीमद्भागवते महामुनिकृते किं वा परैरीश्वर:
सद्यो हृद्यवरुध्यतेऽत्र कृतिभि: शुश्रूषुभिस्तत्क्षणात् ॥ २ ॥
Completely rejecting all religious activities which are materially motivated, this Bhāgavata Purāṇa propounds the highest truth, which is understandable by those devotees who are fully pure in heart. The highest truth is reality distinguished from illusion for the welfare of all. Such truth uproots the threefold miseries. This beautiful Bhāgavatam, compiled by the great sage Vyāsadeva [in his maturity], is sufficient in itself for God realization. What is the need of any other scripture? As soon as one attentively and submissively hears the message of Bhāgavatam, by this culture of knowledge the Supreme Lord is established within his heart.
-SB 1.1.2
