"The mantras are very tiny syllables, but the power locked inside them is tremendous. That is why they are known in Sanskrit as 'seed words' or Bijas. Bija means a seed. The seed carries the whole tree.
Everything that is needed for the tree is contained with the seed. Similarly, everything that is required for your life is contained within the mantra.
I don't see a better way to improve your life other than using mantras. There is no need for any philosophy. All that you need is to just go on chanting. As the mantras take root in your consciousness, they will lead to a beautiful flowering in your life."
