Yawning is not a sign to stop meditating. You can keep meditating even if you are yawning. Being overstimulated, which is painful, is a sign that you are pushing yourself too hard and should reduce the amount of meditations you do until your body adjusts to the energy. After your body adjusts to the higher level of bioelectricity, you can increase your meditations.
Having difficulty visualizing yourself in a white-gold aura indicates your aura is dirty. A dirty aura will cause problems like anxiety, depression, and difficulty with meditation. You need to thoroughly clean your aura until you can visualize the white-gold. You can use the Sanskrit mantras VREEM (vibrated VVV-RRR-EEE-MMM), VI-SUDDI (vibrated VVV-EEE-SSS-UUU-TH-TH-TH-EEE), or AUM SURYAE (vibrate AHHH-UUU-MMM SUUU-RRR-YAH-YAY) to clean your aura if you aura is extremely dirty. If you need help pronouncing the mantras, Satan's Magickal Squares are Sanskrit and Audio Mp3s are in Satan's Library. SURYAE is at the end of the "Sun" Mp3.

If you live near a church and a jewish neighborhood, you need to build a very strong aura of protection to guard yourself against the negative energies of the area. You should clean your aura and build an aura of protection daily at the minimum, multiple times daily is better.
Aura of Protection

http://josministries.prophpbb.com/topic10007.html You can also absorb energy from the sun or visualize yourself in a golden aura and affirm 108 times “I am always safe, secure, protected, and healthy in every way.” The protection working can be done multiple times a day.
You should also build a shield around your room/house. That will keep negative energy and malicious entities out. You can visualize Satanic electric-blue fire filling your room/house and affirm something like, "All enemies of Satan are completely and permanently banished from this house." You can also do a Banishing Ritual every day. If malicious entities are strong, you can do more than 9 vibrations of VINASA for the Banishing Ritual.
