When any branch of knowledge is taken into consideration, two things, because of their significance, immediately become important. The first one is theoretical knowledge, which we possess about that particular branch of knowledge and in its final stage practical demonstration and implementation of that branch of knowledge is observed. In other words, knowledge is the name given to the combination of theory and practice. Like any other branch of knowledge, the spiritual sciences, too, are no exception to this rule, that is, after learning and Rules, Laws, Principle and Formulae Theoretically; they are tested, analyzed and examined practically. There are two possible ways of learning and acquiring knowledge. One method is to learn the theory first and then to use the learnt formulae, principles and laws practically. The other method is to start learning through practical experiments directly.
