舌のわずかな動きだけでかすかに唱え、他人には聞こえず、自らにも微かにしか聞こえないジャパは、ウパーンシュ（upāṃśu・囁きのジャパ）と呼ばれる。だが心中において、音節の連なりを文字ごと・語ごとに繰り返し追い、音と意味の双方を観想するなら、それはマーナサ・ジャパ（mānasa japa・心念の反復）と宣言される。

FAQs
It defines subtler and more inward forms of mantra repetition—upāṃśu and mānasa—showing that japa becomes spiritually deeper as it moves from outer sound to inner contemplation of both the mantra’s vibration and meaning, leading the devotee toward Shiva-realization.
In Linga-worship and Saguna devotion, japa supports pūjā by steadying attention on Shiva’s presence; mānasa japa especially internalizes the worship so that the Linga is honored outwardly while Shiva is remembered inwardly with meaning-filled awareness.
Practice upāṃśu japa by softly moving the tongue so others cannot hear, and progress to mānasa japa by repeating the mantra mentally—syllable by syllable—while contemplating its meaning; this is ideal alongside Rudrākṣa counting and daily Shiva-pūjā or Mahāśivarātri vrata.
