Dear JAMAYA your first question surely has an impressive range and depth to say the least. But instead on harping on I will answer it as brief as I am able to:
Is there a meaning? Indeed there is and in short it sounds like this: "Love the Lord your God with all of your heart and with all of your soul, and all of your mind and love your neighbour as yourself" It may not sound like much, but know that as easy as it is to say as hard it is to understand the full scope of.
Do you know of any other Jamaya's any where else? No I do not know anyone named Jamaya
Unfortunately I do not know what the name Jamaya means if you are wondering about that too. Yet, could it be indian or something alike to that? What nationality do you and your parents have?
