It is not uncommon as the intensity of light increases, for people to be troubled by repetitive thoughts that they would rather not have. Even where worry and obsessive patterns of thinking have not been pronounced before, increased light begins to purify the body by sending energies from both the physical organism and the subconscious mind into the conscious mind. As a result, 'flooding' is often felt or unwanted mental activity.
What is important about this is to know that a purification process is underway. Also that such heightened mental activity often comes in waves that reach peak intensity then subside. While these waves are active and intense, it is useful to know how to bring energy to the heart. Bringing energy to the heart and disconnecting from mental activity allows the releasing from the body to continue unabated, while the conscious self becomes more able to dis-identify with the mind. Thus, a separation is created between one's awareness or point of focus and one's thought process.
To bring energy into the heart, the easiest and most effective route is through sacred breathing which brings light and love into the heart center. Sacred breathing is a means of aligning with God's light and love and in the presence of overactive mental acitivity, it focuses attention on a different energy than the one which the mind carries.
To re-direct energy to the heart, the Practice of Alignment is useful, as is any other spiritual or meditative practice which brings light into the heart center. During times of intense purification, it is important to not force things - to not get into a struggle with one's thoughts, but rather to have a different direction to turn to so that peace and stability can be created, even in the midst of a mental storm.
