looking at particle nature "mass of photon" don't have a simple general meaning as the "mass of a cricket ball".it is some property of photon which comes from quantum mechanics and theory of relativity but not "mass" exactly.That is why we say that photon has ZERO rest mass.

Light is emitted as a photon package when an electron jumps from one orbit to another. This is not the only truth but it is a simple one. Once the light is in motion it follows the universes law for motion and it keeps moving. An object in motion tends to stay in motion...and an object at rest tends to stay at rest.
A light beam is bent by gravity, but as someone already pointed out that is only part of light's nature,the particles are essentially unaffected in their little packages.

my understanding is that light has no mass, is not bent by gravity and is not pushed and is not on a journey.
it is space that is bent by gravity. light just follows space at least from this perspective.
the difference between light speed and an observers speed is always c. this has always suggested to me that light does not move, the observer does. this is not believed by anyone but myself to my knowledge, but questions like yours suggest it.
it seems more likely to me that we move at c in a wave form, than that light does.

Wow.
An interesting question!
Okay, to which nature of light do you refer? The wave flavor, or the particle flavor?
Point is, we still don't know all there is to know about light. The two-slit/duality experiments are particularly (pun intended) intriguing. How does light "know" when it's supposed to behave like a particle (one slit) and when it's supposed to act like a wave (two slits)?
Answer the question that you can control in a lab, and I suspect all the other questions will have obvious answers.

light is not mass it just follows the space time curves caused by gravity lice every thing ells

there is the belief that light is somewhere between
a particle and a wave.
it has properties of both.
