I am assuming you are in Coimbatore to visit the Isha Foundation. It is located between mountains, with lush greenery on all sides. I suggest you leave early morning from your place for your spiritual journey. You can take the local bus from Gandhipuram bus stand, every 20-30 mins you'll get a bus, ticket will cost you Rs.40 or you can go by cab which will cost you approximately 400-500. Once you reach there you have to deposit your bag, phone and other valuables. So I couldn't take any photos, sorry ;) Once you go in, you can watch the introduction video. There are two kunds(poole) one for males and one for females. These pools are energized by rasalingas, which have been consecrated by Sadhguru. For females it is Chandrakund and for males it is Suryakund. They increase the receptivity to the energies of the dhyanalinga. Don't forget to carry towels. From here you can proceed to the Bhairav Linga, go before 12.30 as it closes from 12.30-4.30. Don't forget to attend the yoga sessions, they are free and useful. Then go to the main attraction, Dhyanalinga ( meditation center ). It is absolutely divine and spiritual. Spend your own time in there. There is a canteen where you can eat, next to it is the Isha shoppee, where you can get clothings, bags, interior items, medicines and all. It's a bit expensive though. Now that you are done, go out and walk towards the Adiyogi statue. You can even take a bullock cart ride. It's and amazing piece of architecture, which you must see. And with this your divine journey comes to an end.
P.S. I would suggest everyone to stay at Isha Foundation for one night atleast, you can book a cottage by contacting them prior.
