If your ida & pingala are not adequately balanced before the commencement of formal yoga practice, then i reckon attending to this and making it a priority in the first instance would be sensible idea. If you didn’t attend to this and there was a slight imbalance before starting yoga it could exaggerate or exacerbate any existing imbalances. Once your ida & pingala are nicely balnced, chakras will open naturally as well as sushumna and kundaliini(the divine intelligence or mysterious force behind this potential energy) will be irresistably drawn upwards- the rising will be safe and sound & smooth.Not making this a first priority might not guarantue a safe sushumna and kundalini rising awakening, i.e it could result in a difficult &/or challenging road ahead (although not neceesarily; they might be already balance enough or you just get lucky).Many of the credible systems out there do lay some emphasis or give some importance to it. Just look here for more info:-

The stages are broken down here and the dynammics explained.Swami Satyananda Sarswati in his book ‘Kundalini Tantra’ also talks about it and gives no smal emphasis to it.I’m preety sure you’d find the point brought up again and again within say that book alone just to re-inforce it.Many of the basic pranayamas should be enough to address it if done over long enough timescales as changes are accepted,the nadis adequately purified.
iF you add in meditation with pranayama and light asanas then this wil help stabilise the results, i.e effects of the pranayama and enable you to better detach from the process as it is occuringby fostering inner silence. Just watching the inner silence can be enough for this purpose, as a meditation technique.All you doo there is- find a comofrtable postion, in a seat or upright in a meditation pose,close your eyes ,try to relax the whole body incl. the presure at the temples & eyes.If you wish to turbo charge this or make it more potent you could silnetly meditiate on Om or any mantra divinely revealed or given by a guru or one scientifically trialled and approved perhaps(i.e according to yogic “spiritual” science).
There are practices that can work directly on individual chakras & indeed sushumna. But if ida & pingala are not balnced enough or your mind is unstable or noisy, i.e one thought naturally & quickly moves to another(that is probably a great deal of us from what i can observe and infer;‘normal’ life conditions us that way unless we rouitnely meditate sucessfully) , then either nothing much miight happen or it’s going to be a lot diifcult, potentially slower and may not yeild optimal results for everybody practicing it.A universally sounder & more successful aproach for everyone would be to address the balance of ida & pingala as first priority certainly if this merits adressing.I would just prescribe it for everyone because they may work th chakras incl. the third-eye and even sushumna and make rather slow progress, that’s if their goal is to awaken sushumna and kundalini; allow it to rise.
Some people that just give the focus to working with energy it has been said can end up with same ego, i.e it does’nt suddenly dissolve as some might be thinking,( not that the ego i believe ever really goes away;i think this is pretty naive thinking; we just train ourselvles in identifying with it somewhat less) ,and it may not be the most successful approach so a balanced practice that includes some kind of meditation or quiet silent period(does’nt need to be technical-keep it simple! less IS more) just with the eyes shut (basically doing nothing but with awareness,relaxed & easy!) would be a safer approach especially to cultivate the calm quiet mind that will help with the kundalini awakening process.Just watching the silence allows you to detach as well as recognise the subtle effects as prana is allowed to flow more freely and the subtle bodies open up.
You mayl feel the prana often in an unpurified system, i think,freq. as tiny little currents that can be felt flowing particualrly in areas of previous obstruction or indeed anywhere where the energy is being moved. How do we recognise it? It is very subtle but it just comes with practice & experience.It’s not that difficult. Some experiences are rather profound & bigger; i said here before if you get a big opening say like in the suhumna or a chakra it may feel like you’ve just consumed stimulants or feel rather drunk.Typically you will get third-eye activity, master control centre, whenever, i think the energy may be moving and stirrring.It is felt like sensations at the forehead although they say it’s supra-sensible.The manipura belly burns the fire of impurities and can be quite noticeable and can be quite balancing.BUt to me it just makes sense both from experience and combined with what i’ve read that if ida & pingala are not adequately balanced that you do some things to adress this.
