Yoga not only aids in the prevention and treatment of illness, but also in the maintenance of mental balance and attention. It is found in several studies that Yogic practices like Asana, Pranayama, Meditation and Mantra chanting have a positive effect on our body and mind. The objective of the present study was to see the effect of selected Yogic practices on the concentration of school students in Shimla. The subjects for this study were selected from Himachal Pradesh University Model School, Summer Hill Shimla. A total of 50 students were chosen at random for the study. The Independent Variables were the yogic practices, while the dependent variable was the concentration. A five-point behavioural scale created by Brown and Holtzman in 1967 and refined by Malhotra and Rana in 2004 was used to assess the students' concentration levels. There are 25 items on this scale (modified version) with a split-half dependability of 0.80. A beneficial effect of Yogic Intervention on the concentration level of school kids was noticed after six weeks of regular practice. It is concluded that there is a positive effect at the level of concentration of the students who practice yoga regularly.
