If i use visualization mediation will the nimatta still appear? I'm having trouble truly understanding nimattas. I use visualization for my jhana mediation. It's what focus my mind best and allowed me to almost enter jhana. But if i do visualize, will the nimatta still appear? How would i recognise it? And once it appear do i move off my object to it?

Also i read this passage explaining what a nimtta means in the modern day. I wish to know does this do a great job explaining it.


  Now certainly it is true that if you become VERY concentrated you might see an image that looks like "a star or a cluster of gems" or "chariot wheel or the moon's disk," etc. And it is also true that you can with sufficient concentration absorb into that experience so deeply that you no longer hear sounds, or are aware of your body, or are even aware of the passage of time. This is not what is described in the suttas; however, this is indeed what the later commentaries mean when they use the word "nimitta."
the question is regarding nimittas, following of visualisation . A little effort to answer you,aroused  after  thought giving based on understanding of buddhist teachings after simple teachings of goenka guruji and book by william hart "The art of living-vipassana as taught by goenka". teachings of buddha as per my understanding is very simple. not developing new sankharas and eradicating accumulated sankharas since many lives  and thus attaining shunyata i.e no volitions left (nibbana). to attain this simply observations of bodily sensations arised upon the contact of the sensory bases,remaining neutral i.e not to avert the unpleasant and not to crave for the pleasant ones , and thus slowly weakening the habit of mind of reacting(aversion or craving) and finally totally liberated from the habit/conditioning of reacting of mind.  now in your case the visualisation . who will visualise? the answer is mind and the mind is solely responsible for the suffering. it is master in deceiving and keeping the self engrossed in innumerous nimittas . Afterall how it will allow to eradicate its habit/conditioning which will be its death. buddha has stubbornly discouraged being distracted/engrossed by the so called nimittas,visions,some ecstasic  feeling .   I  have not tried the visualisation bcs from the very beginning i had mis or right conception that , if at all it is matter of visualisation then why not to visualise that nibbana is attained. alas it would have been so simple. hope little bit light upon your question . to add one thing , in indian language the meaning of nimitta means excuse. in english "catalyst" but advantageous in reverse way i.e instead of boosting the chemical reaction the nimitta here retards it . hoping and wishing to you for getting still more right understanding of buddha's teachings and starting the journey.
