Master your mind
Just sharing a gem from my channelled replies to my student...
"You have to learn that your thoughts are just wisps of smoke. You can breathe it in but you can also wave it away. Meaning you can be having the most horrible thoughts about yourself, but you don't need to believe them. Because negativity is part of the human existence. We can not heal it 100%. If everytime we are negative, then we collapse or go hide in cave, then no need to achieve life purpose already."
Just to add, thoughts are mostly the output of childhood conditioning and karmic imprints. These can be healed so that negative thoughts are reduced in intensity and frequency.
However, you can also develop the habit of ignoring your thoughts. Your thoughts are not you. Your thoughts need not dictate your emotions and actions.
Example:
"I am not worthy"... Okok, shrug, moving on!
"I hate myself.".... Hmmm, ok, shrug , I'll accept that for now.
Learn to detach from your thoughts. Acknowledge, accept then let go. You will find that your emotional state will become a lot more stable and peaceful. You can be the master of your mind instead of letting your mind overwhelm you!
