Kūrma Supports Mandara; Hālahala Appears; Śiva Becomes Nīlakaṇṭha
निर्मथ्यमानादुदधेरभूद्विषं महोल्बणं हालहलाह्वमग्रत: । सम्भ्रान्तमीनोन्मकराहिकच्छपात् तिमिद्विपग्राहतिमिङ्गिलाकुलात् ॥ १८ ॥

The fish, sharks, tortoises and snakes were most agitated and perturbed. The entire ocean became turbulent, and even the large aquatic animals like whales, water elephants, crocodiles and timiṅgila fish [large whales that can swallow small whales] came to the surface. While the ocean was being churned in this way, it first produced a fiercely dangerous poison called hālahala.
In Bhagavatam 8.7.18, Śukadeva explains that when the ocean was churned, a terrifying poison named Hālahala arose first from the violently agitated sea.
This verse indicates that the churning initially produced a dangerous, unwanted result—Hālahala—showing that great endeavors may first bring hardship before auspicious outcomes like nectar appear.
The shloka reminds seekers that early difficulties can precede higher rewards; steadiness, faith, and taking shelter of the Lord and His devotees helps one endure the “poison first” phase of life’s churnings.
