Leela means an act or play. Leela were actions of Bhagawan, Saints, Sants, and great masters that were used to teach their disciples different principles and subjects.
The objective of many of their miracles was or is to convey the teaching in a language that their disciple could best understand. However, due to the fact that people differ in their capacity and ability to learn and interpret the happenings around them, the same leela will often have different imports to different disciples and observers. Each disciple draws his own conclusion and learns a lesson for himself from one common context or word of the sadguru.
