Without Tesla's discovery that electrical signals can be transmitted without wires to a receiving antenna and the signal amplified, an adequate metaphor might still be lacking in Buddhism to explain transmigration. In Buddhism, transmigration refers to the cycle of rebirth and the continuation of consciousness from one life to another. Vijñāna, or consciousness, plays a crucial role in this process since it survives the death of the carnal body. Vijñāna can be described as the "knowing" that divides (vi) experience (jñāna) into subject and object, contributing to a false sense of self.
The body however is a transceiver and the DNA strands are an antenna that can both send and receive. The transmigrant signal is vijñāna that represents a wave-like function: a disturbance or difference in the original one (a pure waveless medium, i.e., pure Mind).
The wave with its oscillations, represents the discriminative consciousness (vijñāna) with subject-object duality. Through an intuitively grounded meditation when the wave function reaches a stable non-waving state (samādhi) this is the cessation of dualistic discrimination and nirvana attainment.
But this is only the beginning of the real path, the path of a Bodhisattva. When a sufficient amount of samādhis are accomplished this leads to the light of Mahayana/mahāyana-prabhāsa, a powerful kind of shakti/शक्ति or baptism by pure Mind after which the adept sees the world as it really is for a short period of time until the old habits or vāsanā eventually return.
