SB 9.9.8

ity uktvā sa nṛpo devaṁ
 tapasātoṣayac chivam
kālenālpīyasā rājaṁs
 tasyeśaś cāśv atuṣyata
Synonyms: 
iti uktvā — after saying this; saḥ — he; nṛpaḥ — the King (Bhagīratha); devam — unto Lord Śiva; tapasā — by executing austerities; atoṣayat — pleased; śivam — Lord Śiva, the all-auspicious; kālena — by time; alpīyasā — which was not very long; rājan — O King; tasya — upon him (Bhagīratha); īśaḥ — Lord Śiva; ca — indeed; āśu — very soon; atuṣyata — became satisfied.
Translation: 
After saying this, Bhagīratha satisfied Lord Śiva by performing austerities. O King Parīkṣit, Lord Śiva was very quickly satisfied with Bhagīratha.
Purport: 

The words āśv atuṣyata indicate that Lord Śiva was satisfied very soon. Therefore another name for Lord Śiva is Āśutoṣa. Materialistic persons become attached to Lord Śiva because Lord Śiva bestows benedictions upon anyone and everyone very quickly, not caring to know how his devotees prosper or suffer. Although materialistic persons know that material happiness is nothing but another side of suffering, they want it, and to get it very quickly they worship Lord Śiva. We find that materialists are generally devotees of many demigods, especially Lord Śiva and mother Durgā. They do not actually want spiritual happiness, for it is almost unknown to them. But if one is serious about being happy spiritually, he must take shelter of Lord Viṣṇu, as the Lord personally demands:

sarva-dharmān parityajya
 mām ekaṁ śaraṇaṁ vraja
ahaṁ tvāṁ sarva-pāpebhyo
 mokṣayiṣyāmi mā śucaḥ
