144,000 is a vibrational frequency, the number of harmonic resonance, required to make the "ascension" from a 3-dimensional carbon-based body to a 4-dimensional crystalline-based body, otherwise known as a "light body".
Makes absolute sense to me. I have seen many images representing this. If anyone is interested in knowing more, a good place to start is CYMATICS. This will explain a lot about the effects of vibrations due to the waves. The "Ascension" is acoustical levitation.
This is the kind of body Jesus had after his resurrection, where he could walk through walls but was still able to eat regular food with Doubting Thomas.
