Charity is the best form of prayer. Do whatever little you can to help the not so fortunate. You may donate a small portion of your income, you may take out time to teach the underprivileged children, sponsor a meal for the hungry or just spend some time with an old lady who has no one. I am sure that you will move one level high on the spiritual plane. Like prayers, doing charity once is not enough. You have to do it continuously, as much as possible.
Every individual whom you interact with affects the flow of energy in your body. Some flow with positivity spreading love and compassion, making you happy. Others flow like venom, harming you. The question is what to do with these negative people? Either, you can simply throw them out of your life and not let them affect you anymore. The other way is to have so much positivity and optimism that their negativity is covered up with your energy!
Isn't it strange that what we call "self" doesn't really constitute of our "own". It consists of parts and bits of so many people around us! People who helped us, people who laughed with us, people who wiped our tears, people who walked with us, people whom we looked up to as idols, people who silently followed us, people who hated us, people who challenged us! We are a net integral of all these, isn't it?
