Any damaged or modified organ in the body results in a change in the flow of energy. For example, if you cut your nasal passages, would your breathing be affected? If you cut your esophagus, would eating be affected? Since spiritual development depends upon sexual energy, if the sexual organs are modified, then spiritual development is also affected. The amount of the effect depends upon the extent of the modification.
We recommend against such procedures.
If someone has already had it performed, they can investigate having it reversed. If it is not possible, their only recourse is to appeal to God for assistance.
Of course, someone who has modified, limited, or even lost their sexual function still retains the ability to meditate and work on the ego, and sacrifice on behalf of others in order to help humanity. Great sacrifices and dedication to others well-being, in combination with mystical death, will create enormous benefit for everyone. This is a vitally important work, and can be pursued until a new body is acquired.
