Communication can be done in many ways; the ways vary depending from each and every condition, person and personality. Some communicate through the eyes, some through motions and a few through the thoughts, while many go for the words and hands together.
Love is communicated best through the minds and desires and love itself needs no words to be communicated, if some one loves you, you know it before the person loving you says it. That is true in the event of the love being so true that it can withstand a few tests. Any thing taken for granted does not stand the tests of time; hence not even love should be taken for granted. A love should be tested to for its classification and quality.
Love originates out of desire in ordinary humans, love is existent in every form, and animals too exhibit love. Dogs for instance considered the man's best friend is said provide the master with an unconditional love. Like it is a dog is a dog and an animal an animal and human though being an animal but a better one among the animals, should exhibit better love, than the ones observable in animals.
An animal love begins with certain desire and so does human love. Animal love does not end with the end of desire, as an animal never stops desiring, so does every human, but control on desires and being desire free is considered as one the most superior qualities of human kind.
Superior human isnt one who has no desires as what so ever, but the one who can love any one, without any selfishness, or the desires is said to be the superior of all humans.
Normally great sages and few great people are attributed to be the superior humans, simply because their actions reflect up on the selflessness.
God is also defined as someone who created us all and sees no difference in his creations, he loves them all and forgives them, all religions has this concept with almost no difference in the way god has been defined.
To love is to being an gods creation and to love without any selfishness and desires is to being superior humans and to be more accurate, loving anyone and may be everyone, without the desire and expectation is being god.
