Guiding Thoughts

The above link is to a article posted on scribd. It may answer your questions. In my personal view we go to a temple as the atmosphere in most temples is calming. Every one comes to a temple with clean thoughts(relatively clean) and so the thoughts in the atmosphere induce mental peace and stability and give hope. We go a hospital - because everyone there is also looking for some solution to a problem and there is someone (a doctor) who knows enough abt the subject to solve it. You may find this article interesting. If you are highly evolved and can find God in your own self and others around you- i guess the need may not necessarily arise. Most sages / Rishis were their own temple. Thats my view.Great question- i wondered abt it myself

You can try doing the Gayatri Mantra, and each time you think of this persistent thought- you can try replacing with a thought of Happiness Success. It requires effort, but it helps. There are some dhyaan videos I am refrencing here. You can hear them (they are 20 mins each and the Dhyaan is enclosed at the end of the video). There are 6-7 dhyaans and u choose the one that resolves your specific issue. I hope it helps u out.
