Many of the mantras and prayer are in Sanskrit . I know many sages and gurus reiterate that the benefits are manifold when the mantras/slokas are chanted with understanding of their meaning.
In that context, is is okay to read Chandi or any scripture in English than Sanskit. Is it okay to chant a mantra in "English meaning" form than transliteration or original sanskrit form? will the benefits be same ?

Swamiji says: It is definitely important to understand what we are saying.
When we recite the Sanskrit sounds, we get great benefits on many levels. When we recite with understanding we get even greater benefits on many more levels.
It is more than OK to recite the translations as well as the original texts. It is preferred. After some time of reciting both the Sanskrit and the translations, we will find the correspondence between the two, and intuit the meanings on a multitude of levels.
Highly recommended.
