In that condition of spiritual consciousness, the contributor, the contribution, the consumption, the performer or leader of the performance, and the result or ultimate gain-everything-becomes one in the Absolute, the Supreme Brahman. BG 1972 purports

BG 4.24, Purport:

The word brahma (Brahman) means "spiritual." The Lord is spiritual, and the rays of His transcendental body are called brahmajyoti, His spiritual effulgence. Everything that exists is situated in that brahmajyoti, but when the jyoti is covered by illusion (māyā) or sense gratification, it is called material. This material veil can be removed at once by Kṛṣṇa consciousness; thus the offering for the sake of Kṛṣṇa consciousness, the consuming agent of such an offering or contribution, the process of consumption, the contributor, and the result are—all combined together—Brahman, or the Absolute Truth. The Absolute Truth covered by māyā is called matter. Matter dovetailed for the cause of the Absolute Truth regains its spiritual quality. Kṛṣṇa consciousness is the process of converting the illusory consciousness into Brahman, or the Supreme. When the mind is fully absorbed in Kṛṣṇa consciousness, it is said to be in samādhi, or trance. Anything done in such transcendental consciousness is called yajña, or sacrifice for the Absolute. In that condition of spiritual consciousness, the contributor, the contribution, the consumption, the performer or leader of the performance, and the result or ultimate gain—everything—becomes one in the Absolute, the Supreme Brahman. That is the method of Kṛṣṇa consciousness.
