Einstein always meant what he said!

Look again at the equation – E=mc2. Energy equals mass times the speed of light multiplied by itself. Let’s set aside the c2 part for now. We are left with energy equals mass. What has mass? Matter has mass. Therefore, energy equals matter. Or matter equals energy, whatever makes you happy. The bottom line is that matter and energy are the same thing. Well, it's the "same thing" similar to the way ice, water, and steam are the same thing.
To understand this clearer, let’s take into consideration various types of energy. Heat energy for instance. Heat as you know is measured in degrees. The intensity of the heat, or lack thereof, is measured along a scale, either in Fahrenheit, Celsius, or Kelvin. Heat is the result of atoms vibrating rapidly. The more rapidly they vibrate, the more heat energy generated.
How about sound? Sound is made when energy travels through the air. The amount of energy will determine how loud or soft the sound is. Variations in that energy will determine the pitch, like the keys on a piano.
Finally, let’s look at light energy. Light energy actually contains many distinct manifestations. Rabbits Mate In Very Unusually eXpensive Gardens. That is, Radio, Microwave, Infrared, Visible light, Ultraviolet, X-ray, Gamma. You may recall seeing a picture of the light wave on which, depending on the frequency of the wave, would manifest itself in the variations memorized through a comment about the sex lives of lagomorphs. In a narrow frequency range somewhere in the middle of that huge wave, you find all the colors we know, all the sights we’ve ever taken in, and all our eyes have ever seen, or not seen.
Getting back to the equation; we found that matter and energy are the same thing. So it only makes sense that matter is found somewhere on a wave of energy not unlike heat, sound, or light, with matter on one side, and pure energy on the other. And let’s not forget the c2 part of the equation. Given that the speed of light times the speed of light is a very large number, and given the vast difference between matter and energy, the two are likely separated by an equally vast expanse of energy wave.
Just as we see visible light, we exist in experience-able matter. So on one end of the energy/matter wave is pure energy, on the other - matter. The closer or further matter is to pure energy will determine the manner by which matter will manifest itself. Similar to the way light will manifest itself in different colors depending on the frequency of the light wave.

Keep this in mind from here on out. We're at the threshold of the meaning of life.

It means that all energy transformations in the world are associated with a change in mass.
Example:
If you lose 1000 Joules by doing some work, you loose 1000/(3*10^8)^2 Kgs (=1.11*10^ -15 Kgs) of weight

The second formula is used to describe at what rate mass diminishes as energy is released, or how much mass is lost by generating how much energy... What don't you understand? You pretty much answered you own question. It's sorta like mile/gallon, in lay mans terms

Einstein's equation is E = mc2 now if we consider the lost energy as E1 and lost mass due to loss of energy as m1 then lost energy E1= lost mass m1x c2 but in ur second equation u have put L in place of E1 so the equation is L =m1xc2 now converting this equation for the value of mass comes to
m1=L/c2 thus the second equation is a derivative of the first equation.
you may come to same result by E-E1 = (m-m1)xc2 then we have subtracting this equation from original equation
[E=mxc2] - [E-E1=(m-m1)x c2] then also u get [E-E-(-E1)] = [m-m-(-m1)]xc2 therefore E1=m1x c2which means m1=E1/c2 replacing m1 by L u get L=E1/c2

E=mc2 what formulated by french physisit and mathematician ;
Henri point Carre .I dont know what view was assigned when there is a mass loss..
Einsteins relativistic mass equations refer to a mass increase rather than decrease with velocity.
