Inner Attainment Through Kasab
"When we trace that the source that holds life is nothing but light then we realise that the nature of light is to extend its rays and spread them around it. So it is with the light of the soul. The soul spreads its light, which is breath, and extends it to the right and left. By that all things external become lighted, that both the eyes and mind may see. But when this light instead of extending, is concentrated, so to speak, instead of spreading is thrown inward, then it lights up the inner planes and all that is there becomes clear.
This is done by Kasab, for in Kasab one masters both the power of light, in extending and throwing them inward and thereby in time develops the light within which guides the path toward the journey within."
Hazrat Inayat Khan
The morning is the best time for practicing Kasab. The rhythm in kasab is not the same as in Fikar. In kasab, there is retention, between the in-breath and the out-breath, and this interruption of the natural flow of breath is done differently according to each individual. This practice is in itself a preparation for higher practices.
Kasab may be done in a Jelal, Jemal or Kemal pattern, and by this experience, the perception of those influences can be developed.
All these characteristics of the elements may be seen in the breath, which is influenced accordingly at different times of day and night. When exhaling upon one of the five elements, one may project upon the chosen element all negative vibrations, allowing the inhalation to return in a purified condition.
