Someone may have longevity but not have auspiciousness or good behavior. Someone may have both auspiciousness and good behavior, but the duration of his life is not fixed. Although such demigods as Lord Śiva have eternal life, they have inauspicious habits like living in crematoriums. And even if others are well qualified in all respects, they are not devotees of the Supreme Personality of Godhead.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
क्वचिच्चिरायुर्न हि शीलमङ्गलं क्वचित्तदप्यस्ति न वेद्यमायुषः । यत्रोभयं कुत्र च सोऽप्यमङ्गलः सुमङ्गलः कश्च न काङ्क्षते हि माम्
kvaciccirāyurna hi śīlamaṅgalaṃ kvacittadapyasti na vedyamāyuṣaḥ | yatrobhayaṃ kutra ca so'pyamaṅgalaḥ sumaṅgalaḥ kaśca na kāṅkṣate hi mām
