I'm still unclear about what this ability is, can you explain more about it? Do people feel different when they are around you, or when you start giving love and blessing people?
My understanding is that people with high Levels of Consciousness (LOC), such as enlightened people, or even people at Love/Unconditional Love, radiate Grace/Holy Spirit/Shakti/Kundalini energy as the Presence of God within the aura/field/physical presence. This energy is what changes people as they come within your physical presence. It isn't the physical/mental act of loving/blessing people that really does it (though intention certainly does help), but just the natural consequence of God's Presence within the aura of high LOC people. It isn't something you can control or improve as an ability, you can say -- it just happens by itself.
To get "better" at it, you raise your own LOC, and by raising your own LOC you help raise mankind's LOC as well, as that spiritual energy radiates from you into the world. It's not "improvable" like a skill, but with serious spiritual work your spiritual energy capacity does increase as your LOC increases. So all that is needed is for you to seek your own enlightenment and raise your own consciousness, and by doing so you will help all of mankind raise their LOC.
So yeah, if you want to dedicate your life to doing spiritual work and raising LOC, kudos to you
It is my life purpose as well, hope we can help each other on the path.
