The powerful fragrant scent of incense is supposed to purify the mind, body and spirit. During religious rituals and other ceremonies the scent rising upwards is supposed to take our prayers, requests and gratitude towards heaven. We find a very important and surprisingly similar correlation to lighting incense and religious ceremonies all across the world across various religions and faiths.
It is said that when "Three Wise Men" came to see baby Jesus- they had lighted Frankincense & Myrrh and even to this day it is a common practice to light these incense aromas in many churches across the world.
Thus we find the usage of Aroma Therapeutic principles throughout ancient times via not only the use of essential oils but also incense in various forms. Incense is probably the least intrusive and at the same time a very effective means of administering various aroma therapeutic benefits. It provides a "pleasant ambience" for an evening of relaxation, or clears one's thoughts and helps in focusing the mind, for studying all through the night before an exam.
Typically, you will find the right fragrance, which appeals to your sense buds and also at the same time, allow you to achieve your needed therapeutic benefits in the age-old form of an incense.
