think of it this way
If u have a golf ball and u accelerate it to the speed of light, can u see it.
No because it is moving too fast.
if u put your hand in front of it, what do u think would happen?
It would release energy in the process of slowing down, and that'll leave a mark.
so it no longer has mass in your reference plane but it sure has energy.

Neither mass nor energy are absolute but depend on reference frame.
You already know this if you think about it. If you throw a 2 kg ball at 10 m/s on a train it has energy 100 J relative to the train. If the train is travelling 90 m/s then the ball has energy 10,000 J relative to the ground.
But in simple classical mechanics you could just work this out by adding the energy due to the two motions. What special relativity tells us is that - because everyone gets the same result for the speed of light - as the combined speed gets closer to the speed of light some of this energy when added up goes into mass instead.

Energy is required to put mass into motion, energy does not move with motion per se.

Not really....of course, matter can be converted to energy as per E = mc^2 , but that will not answer your previous question...
What you need is a course in Electromagnetism...
it is there that you will learn that the ELECTRIC and MAGNETIC fields of a LIGHT WAVE interact to carry MOMENTUM.
Most posters failed to address that key issue.

mass is not energy, but energy can be converted into mass, and the other way around. e=mc² is the energy produced for mass being converted into energy.
