“Love looks not with the eyes, but with the mind; And therefore is wing'd Cupid painted blind. Nor hath love's mind of any judgment taste; Wings and no eyes figure unheedy haste: And therefore is love said to be a child, Because in choice he is so oft beguil'd.”
― William Shakespeare, A Midsummer Night’s Dream

“based on my personal experiences. Theoretical exposition is mostly my own but the majority of the base concepts are traditional and time-honored views of remarkable sages who existed before me. Therefore, if you wish to read more on the mantra sadhana, you can check out the following texts that I grew up reading. With a bit of research, you should be able to get your hands on good translations. I know that Hindi translations must be available for most of these books and English translation only for some. This is not your standard bibliography with publishers and translators, for I don’t have much of that information. Nevertheless, I’m sharing with you the names of various books you can read to know more about mantra yoga. In particular, I would like to acknowledge the translation of Mantra Maharnava by Ram Kumar Rai, Mantra Rahasya by Narayandutt”
