Srimad Bhagavatam 1.13.55

1.13.55

विज्ञानात्मनि संयोज्य क्षेत्रज्ञे प्रविलाप्य तम् । ब्रह्मण्यात्मानमाधारे घटाम्बरमिवाम्बरे ॥ ५५ ॥

vijnanatmani samyojya ksetrajne pravilapya tam brahmany atmanam adhare ghatambaram ivambare

vijnana
purified identity
atmani
in intelligence
samyojya
perfectly fixing
ksetra-jne
in the matter of the living being
pravilapya
merging
tam
him
brahmani
in the Supreme
atmanam
pure living being
adhare
in the reservoir
ghata-ambaram
sky within the block
iva
like
ambare
in the supreme sky.

Dhrtarastra will have to amalgamate his pure identity with intelligence and then merge into the Supreme Being with knowledge of his qualitative oneness, as a living entity, with the Supreme Brahman. Being freed from the blocked sky, he will have to rise to the spiritual sky.
