The other day Eljas was very concerned for a 3 year old boy that has disappeared in a forest. I told him that the best he could do was to go our alter and pray for him. Now I wonder is there any use of prayers beside the good feeling we might get out of 'doing something' to help?


In Buddhism prayer or doing zazen is not done for something.
It is prayer in one's own mind.
If you are praying in a full hearted way, then this full heart is being expressed and shows itself in everything.
That is how prayer is experienced in Buddhism.
