This is very easy to do.  I teach  my students to do this as soon as they awaken in the morning.

Ask
your protectors/angels/Divine   to surround you in the bubble of Divine light. (you can also say the love and light or a bubble
of white light).  With your intent that only positive, love and light may enter in my bubble of protection.  Negative energy may not
enter.

While visualizing the bubble you also can say:

The light of God surrounds us, The love of God enfolds us, and The power of God protects us, The presence of God watches over us, Wherever
we are, God is.

The important thing to remember when you do this or any other form of protection with the light, is that you must stay in positive
in thoughts, words and deeds.     The light will not protect those that are standing behind the shield of protection and doing harm
to another.

Please note that if the audio at times does not come out clearly the first time.  This can be due to not having a high speed
connection.  I do not have high speed so what I do is first play it though on mute (no sound) then my computer has down loaded
all the info.  Then I replay it with the normal volume.  Not all may experience it but just in case this should happen you will know
how to correct it to make it work.
