Spiritual and Masturbation

[Infinite]

Is it true that masturbation impedes spiritual progress?

Is a very relative question. Depends of your concept of  "spiritual progress".

And that no spiritual master or guru masturbates?

Yes. A master or guru must have total control of yourself and transcended the sexual desire.

I feel like when I do that that I'm giving into fantasies.

Depends of the fantasy intensity . It's possible projects to the "target" (if you desire someone real).

Or do some use the masturbation to build energy and work with that energy?

It's the other way around. The objective is to accumulate the sexual energy to work with it.

What about masturbating for pleasure, does that somehow dampen your spirituality?

Like I answered in top.

Does it go against a discipline of the personality?

It's a normal habit in a population that suffer a lot of influence in the sexual center. The energy must be discharged.

Peace, love and light.
