Start to pay attention to the details in each moment, both inside and outside. Slow down. Look carefully at everything, noticing the distance between what you perceive and the inner source of perception. Become aware of the difference between attention and thoughts, feelings, and sensations. Deepen and extend the awareness of that distinction.
Chant a mantra all the time, alongside everything else you do. In this case, I recommend you pick one of these:
S M Hon
Gate Gate Paragate Parasamgate Bodhi Swaha
Do not consume caffeine or sugar of any kind.
Most of all, pray continually, and use your imagination to feel the presence of your inner divinity.
Be patient, Genuine change is slow.
"Do not worry; cultivate the habit of being happy." - Samael Aun Weor
