As travelers we gravitate to places that are aesthetically pleasing, or culturally, historically, or religiously significant. These places also happen to be focal points of more concentrated energy, or expressed otherwise, areas where the energy that is present everywhere in the world is more readily experienced by humans.
For this reason, this meditation works best in places of immense natural beauty or of religious, cultural, or historical importance. For the former, I usually zone in on the sensual aspects, the sights, sounds, smells, and feelings of the environment while simultaneously remaining aware of my breath. For the latter, I also try to visualize those events or ideas that made this sight sacred or significant to humans, and all those visitors who've journeyed there to stand in the same place. Many of the world's holiest sights, greatest temples or monasteries, and other man-made wonders also happen to be found in locations of stunning natural beauty, and that is no coincidence, so oftentimes you can find both types of energy in one place.
Ideal places can also vary by person. If you find artwork inspiring, meditate before paintings. If you love the buzz of a noisy crowd, then try meditating on the sights and smells of a busy market. If you feel at home in the mountains, then meditate on the tress and vistas next time you are hiking rather than thinking about what you are going to do tomorrow or once you arrive at the next rest stop.
Breathing mediation is also great when eating. Close you eyes and take deep breaths while you focus your mind on the smells and flavors of the food; ponder the sources of those ingredients, the process by which they got to your table, who prepared them for you, and so on. Don't be surprised to find that the food tastes substantially better once you simply pay proper attention to it.
Earlier in my travels I used to consciously remind myself to do breathing meditation whenever I found myself in an appropriate place, but over time I found I would automatically go into that state of breath awareness without even thinking about it every time I found myself somewhere inspiring.
Next you can take this travel meditation a step further by applying it to your daily life — to meditate on the not-so-obviously beautiful or amazing places, such as city streets, the view from your bedroom window, or even your bathroom. Because there is beauty everywhere, and we are always connected, we just need to pay attention to fully experience it.
