If the purpose of doing a practice is to obtain happiness or to chase away suffering in this life, it is an unwholesome motivation. Although it is better than not having faith in the Buddha’s teachings or being indifferent to cultivating virtue, it does not lead to enlightenment. Thus, practitioners seeking liberation from samsara must not harbor this kind of motivation. It is also stated in the scriptures that such motivation must be given up. So every time we do something good, we should always check our motivation first.
