Yes, it is correct if you pray to Lord Siva on full moon day, you will see changes in our life. It will give you a good, peaceful mind. Until three years ago, I went so many times to Tiruvanamalai girivalam, I got good changes in my life. Now I am in Singapore, working as engineer. So all try to pray the Lord Siva in Tiruvanamalai.
I started my first girivalam around 2002. Initially, I got some trouble (in Tamil they says sothanai. It means problems). After 3 months, I got turning point in my life so I decided to go continuosly. During that period I felt very happy and also good things started to happen in my life.
Initially, walking condition very bad but it gave me good experience. Now they improve a lot. So there is no problem for walking conditions i.e. if you can walk continuosly for more than 4 hours.
Between 2002-2005, may be I missed 6 to 8 full-moon girivalams because of my college examinations.
If you want money, go to Tirupati.
If u want to know what is the life, go on girivalam
I will always prefer girivalam. You can get good things in your life with some difficulties, but it will stay permanently with you.
Lord Siva greater, so you please go to girivalam.
Now I am in Singapore so I am missing girivalam.
I want to share one more thing. I always finish my girivalam within full moon period (for e.g. full moon day start around 8.30 p.m. and end 4.30 a.m., I will start after 8.30 p.m. and finish before 4.30 a.m.)
Thanks to you, you gave me chance to tell about the girivalam.
