Dear Eva,
Thanks for taking interest in the HLS.
It acts like a reservoir of Light and/or a energy bank/reserve.
It does not self generate, though one can attune it to send light. It does need polishing, cleansing etc just like us. A kind of mega chi-ball.
If this is so, why do we send energy to the HLS and to those on the distant healing list? Wouldn't it be enough to send healing energy to the HLS?
Both are two distinct means to me. Some may feel otherwise. No problems.
Now I am querying you on the same point.....
Don't you feel good when somebody inquires, "How are you?" or asserts that, "I will pray for you."
On the other hand what do you experience when somebody living below the same roof ignore you...

I mean not helloing you(they may be loving u)

??
I hope you got your answer. Thats the whole purpose of reciprocating on the Distant Healing page.
I know members do send healing, but do not feel the need to make a post. I feel the contrary; My words can reassure the person requesting, so can yours. It simply accelerates the healing process.
The forum is not just for attunements, its also a platform for healing, sharing thoughts & energy, socializing, joking, discussing recipes, whatever within the ethics & code of conduct set by the founder. There are threads made for everything.
If some are coming for just freebies or a just take & be safe attitude, I am afraid its not working for their spiritual development.
Each one's time is precious.I understand sometimes one is too busy, but its also the other way round many times.
Am I going off track too much.........
By the way, I read here somewhere that unwanted energies could try to suck up energy or that when you call down on the energy when ever you need it, you could get some unwanted entities coming in. What truth is in this? Although, I believe that where there is divine energy other forces have no power what's so ever. I think if anything other than love tries to get in, it will simply just get dissolved by the power of the divine. Just my thoughts there.
Unwanted energies do come in the way time to time. History says so. Personal experience too. But as you say, the divine will dissolve it & win.
HLS too had distractions

, but thats been taken care of.
Thanks again Eva for asking.
Be Blessed.
