SB 12.5.10

codito vipra-vākyena
 na tvāṁ dhakṣyati takṣakaḥ
mṛtyavo nopadhakṣyanti
 mṛtyūnāṁ mṛtyum īśvaram
Word for word: 
coditaḥ — sent; vipra-vākyena — by the words of the brāhmaṇa; na — not; tvām — you; dhakṣyati — will burn; takṣakaḥ — the snake-bird Takṣaka; mṛtyavaḥ — the agents of death personified; na upadhakṣyanti — cannot burn; mṛtyūnām — of these causes of death; mṛtyum — the very death; īśvaram — the master of the self.
The snake-bird Takṣaka, sent by the curse of the brāhmaṇa, will not burn your true self. The agents of death will never burn such a master of the self as you, for you have already conquered all dangers on your path back to Godhead.

Real death is the covering of one’s eternal Kṛṣṇa consciousness. For the soul, material illusion is just like death, but Parīkṣit Mahārāja had already destroyed all those dangers that threaten one’s spiritual life, such as lust, envy and fear. Śukadeva Gosvāmī here congratulates the great saintly king, who, as a pure devotee of Lord Kṛṣṇa homeward bound to the spiritual sky, was far beyond the reach of death.
