Bhagavad Gita 2.72

एषा ब्राह्मी स्थितिः पार्थ नैनां प्राप्य विमुह्यति। स्थित्वाऽस्यामन्तकालेऽपि ब्रह्मनिर्वाणमृच्छति

O son of Pritha, this is the eternal state, the Brahmic seat. Attaining this, one is not deluded. Being established in it, one attains oneness with Brahman even at the end of life.
