Question: Guru, how can I get inner strength?Sri Chinmoy: In your particular case you can get inner strength by absorbing more purity in the physical and more light in the mind. You have to pay more attention to physical purity and mental light. Do japa, the thing that is bound to increase your physical purity and mental light. While walking along the street, or in the subway, or if you don't have anything most important to do during your work, repeat the name of the Supreme. Repeat the Supreme's name inside your heart, in silence, and each time you repeat it try to see with your open eyes that the letters S-U-P-R-E-M-E are being written in golden letters on the tablet of your heart. Then light in the mind and purity in the physical will come, and automatically your inner strength will increase.
