It is important during a Tantra session that all of your senses are involved and awakened. So it is vital to create a space to practice that is visually and emotionally stimulating.
For example to stimulate your aural senses soft music played in the background can take your mind to different places. To excite your visual senses, bright colors and candlelight can either be stimulating or calming for your eyes depending on the required experience.
Incense and essential oils affect your sense of smell and open up your energy centers. During the Tantric experience even your sense of taste can be influenced, with delicious snacks to delight the tongue - such as soft, succulent fruits like fresh grapes, cherries, strawberries or dried fruits like raisins and figs etc.
