I only use a shield of light and it works great for me. Thank you

Third verse of the Tao Te Ching

Not praising the worthy prevents contention,
Not esteeming the valuable prevents theft,
Not displaying the beautiful prevents desire.

In this manner the sage governs people:
Emptying their minds,
Filling their bellies,
Weakening their ambitions,
And strengthening their bones.

If people lack knowledge and desire
Then they can not act;
If no action is taken
Harmony remains

If your waiting for the worst then it will come.
The best protection is passive ,transparent,yielding,flowing. seemingly nothing at all.
peace

Why would we need psychic protection to live? And that's precisely what manifestation is - life, good or bad happy or sad all events we have lived through in the past, are currently living or will live through in the future are manifested by us. If you've managed to manifest your life so far without any psychic protection then you definitely don't need in the future.

The only protection you need is to make sure that you attract good and wish good for others because if you wish others bad then you manifest that into your own life.

If your thoughts are not pure and positive, there is nothing that can protect you from attracting negativity as that will be your dominant vibration.

Resist ye not evil.
