You can Most certainly Help others Through your Thoughts.
Every good Thought you send To another is a Living Force.
However, The person you are Sending The thought To Has To be asking For The same Thing you are Sending.
If The person doesn't want it, Then They are not in Harmony with your Thought Frequency, and It will not penetrate them..
You can't Create in another's Life against Their will, But if it's something They want, Your Thoughts are a Real Force That Helps Them..
