Hello Alexandra, I to am junior member to SFQ, though i have been meditating using different modalities, for many years. I am a senior in age, i was looking for help in self-healing and regrouping so to speak my meditation practices.
SFQ, i have found very flexible and that is the beauty of it! In such a hectic world today, it IS hard to find time. It is perfectly o.k. to stop and take off sweater, take bathroom break, get drink of water etc.. It is o.k. to do 2 20min. sessions. ( in meditation,guided, Master Lin says it is best to get in at least 28min. to have the subliminal really take affect), If you are using a meditation to quiet mind, you can try just closing eyes, and focus on deep breathing, sometimes 5 mins. through out day.. to keep a sense of calm between lessons.
I am close to someone that had trouble visualizing his energy light until he pictured it as the sun. I have used candle flame, try any kind of light, led, another visual i use to use is my belly being a hill and the sunrise coming to the surface and eventually spreading out to encompass my whole body... feel the warmth...try energy as a river, or blood flow through out body( BUT as golden light...
I understand, i hope i helped a little! have fab. day!!! namaste'
