I would like to explain the powerful form of japa meditation based on my experience.. I would strongly and wish that everyone would do this for its enormous power. Three aspects are needed in this process ,- A favourable deity A moola mantra ( chant ) for that deity Visualisation and love for the deity. Firstly,choose a deity,it can be of your free interest ,be it Lord Shiva,Krishna,Durga Amma,Hanuman etc.... Then ,learn the moola mantra ( 'Moola mantras' are very powerful core mantras which contain the essence of the mantras pertained to a particular Hindu God / Goddess . The word moola itself denotes base or root. It is highly beneficial to perform mantra saadhana on such mantras. Regular and systematic chanting of the moola mantras of your favorite God / Goddess helps to strengthen the feeling connection with the deity. Once you attain mantra siddhi of the moola mantra, it will then come to your rescue later on by a single chant itself. Each moola mantra has specific benefits.) for that specific deity.For example,- Om Namah Sivaya for Lord Shiva. Then,sit in meditative posture,close eyes and visualise the deity.Understand and accept that the visualisation is not an illusion and that the deity is right present with you through the visualisation.Then,with unconditional and overflowing love,chant the mantra continuously.Make it a meditative state.Let no other thoughts enter the mind..As you chant,shower your love to the deity with holding the visualisation of the image of the deity with eyes closed. For instance,if it was Durga amma,express love as how you would show to your mother.Know that Durga ma is in her motherly form present there as you visualise and you lovingly chant the mantra to her.COnnect with her.Make your chantings be pregnant with enormous love.If tears flow,let them.. these are satthvic feelings which are blissful.. I would encourage all to practice this japa for devi mata during these auspicious navarathri period.May we all be blessed by the divine mother's energy.You can choose the mantra for any form of the goddess- Kali,Durga,Meenakshi etc.. .. Here are some lists of the moola mantras : Enjoysmile emoticonPlease do not do it with an immense feeling of gaining some powers etc... do it with full love and devotion..if it does not come... simply keep chanting.. it would lead to the blossoming of blissful and divine love,unexpressable beauty from withinsmile emoticonI would love everyone to experience such blisssmile emoticon DURGA AMMA MOOLA MANTRA : OM SRI DURGAYAI NAMAH KALI AMMA MOOLA MANTRA : OM KREEM KALIKAYAI NAMAH LORD GANESHA MOOLA MANTRA: The following Lord Ganesha Moola Mantra should be chanted 108 times for 41 consecutive days.
