Enhancing akash means moving towards your original nature, both spiritually and physiologically - when the spiritual longing overrides all other needs. When akash is the dominant element in your system, physical aspects become less important. This does not mean neglecting physicality but transcending it. Transcendence means to rise above present limitations. People generally define themselves based on their racial, religious, national, or gender identifications, or personality traits. Essentially, you define yourself through your limitations, or the boundaries that you have set for yourself. Increasing the proportion of akash and turning spiritual means defining yourself through boundlessness. And boundlessness does not have any definition.
Once your perception rises beyond the physical nature, there is no male or female. There is just a human form that can be made competent in many different ways. Competence is not just in terms action but also perception. You can increase your competence not only as a person but as a life. You can become more alive. Every human being is capable of knowing life in a larger dimension. The aspiration to transcend is latently present in everyone. If you give yourself some time off from your office, family, friends, social media, phones, and computers, you will realize the need to transcend your present limitations. This does not require any teaching or goading. Every human being will know the limitations of their existence if they give themselves the needed time. Once you become conscious of your own boundaries, the longing to go Beyond is a natural outcome.
