The Architecture of ‘Conditional Immortality’
तेन तप्ता दिवं त्यक्त्वा ब्रह्मलोकं ययु: सुरा: । धात्रे विज्ञापयामासुर्देवदेव जगत्पते । दैत्येन्द्रतपसा तप्ता दिवि स्थातुं न शक्नुम: ॥ ६ ॥
tena taptā divaṁ tyaktvā brahmalokaṁ yayuḥ surāḥ dhātre vijñāpayām āsur deva-deva jagat-pate daityendra-tapasā taptā divi sthātuṁ na śaknumaḥ
诸天因希兰尼亚迦西布的严酷苦行而被灼烧、极度不安，遂离开各自天界，前往梵天界，向造物主禀告：“噢，诸神之神、宇宙之主！他头顶所喷涌的苦行之火灼烤着我们；我们无法安住本界，只得来投靠您。”

Because Hiraṇyakaśipu’s intense tapasya generated unbearable heat and disturbance, making it impossible for them to remain in Svarga, so they fled to Brahmaloka for relief.
Hiraṇyakaśipu’s austerity was aimed at gaining extraordinary boons, and Brahmā is the cosmic administrator who grants such boons; therefore the devas appealed to him as the immediate authority to address the crisis.
Power gained through discipline can strongly affect others; therefore austerity and determination should be guided by dharma and devotion, not by ego or harm, and one should seek higher guidance when imbalance arises.
