Luckily, there are leverage points for this. Our neurotransmitters are heavily influenced by certain foods and drinks.
Two are Dark Chocolate and Black Coffee. Two others, not quite as widely available but you can order them HERE, are AFA Blue Green Algae and the tonic herb He Shou Wu.
In different ways, these subtly effect which neurotransmitters are held in our bodies longer. They can act as mild gatekeepers to stress. Sometimes, for some people, the effect is intense but some may experience it on a less pronounced level.
When stress is down and awareness is up, you can more easily know who you are beyond the physical sense of self. This is because who you are in a feeling sense is much more pleasure-oriented than the typical sensations of physical life. These substances can help to bring you closer in a physical sense to this so that your spirit is easier to connect to.
By consciously consuming any of these and meditating on the sensations inside, you can notice a level of elation emerging and your heart becoming more activated.
Those who cannot have any stimulating items should go more toward blue green algae and he shou wu as these can be adrenal supportive.
Some may find occasional use of dark chocolate and coffee to be useful items for reconnecting to spirit as long as they produce more elation and calmness than excessive stimulation (depends on the person).
