And, because it has no need to be expressed, there is no risk.  The heart is not given away, so it does not feel vulnerable.  The lack of pain and risk preserves the state of bliss.

 There is also no need to ever receive anything from the beloved.  If he or she is not aware of the lover’s existence, it makes no difference to the lover.  He or she is content to love on, alone.

 To the lover, it is the love he or she feels that is precious, moreso than the beloved.  Therefore, the love is easily transferable to a new beloved.  In fact, one can feel brotherly love toward any number of people, at the same time.  It is not exclusive to one specific individual, as with Love: The Passionate.

 As Emily Dickenson wrote:
"My business is to love.  The mere sense of loving, is joy enough."

Love: The Brotherly is defined as an internalized loving feeling about someone, which inspires a feeling of contentment and peace.
