Everything begins in the mind with one thought and then a web of thoughts which bind us down. If thoughts are constantly negative, they affect mind and eventually the physical body. Dr. Bach believed that the mind played a major role in maintaining physical health and came to a conclusion that there are 38 states of mind, which affect the peace of mind.
These 38 remedies are for fears, anxieties, stress, depression, guilt and so on. He divided them into 7 groups to study and understand them better. He also believed in the simplicity of the entire set of remedies - his vision being that every household should have one Bach kit in their medicine chest.
The remedies work extremely well with animals too. Children find so much of ease while growing up if the remedies are given to them. Ranging from teething and puberty to marriage and menopause and for every shift and change, since everything begins at the mental or emotional level.
