The main difference between Esoteric Buddhism and Jodo Shinshu Buddhism

Question:

Please tell me in a few words the main difference between esoteric Buddhism and Jodo Shinshu Buddhism.

My answer:

Both Dharma Gates are true and both aim at attaining Buddhahood for oneself and all beings. However, they differ in the means of attaining it. For example, Esoteric Buddhism thinks they can attain it in the present body, while Jodo Shinshu says it will be attained in the Pure Land.

If you want to attain Buddhahood in this body, then you can try the advice of Kobo Daishi, the founder of Shingon (esoteric) Buddhism:

"Form mudras with your hands,
recite mantras with your mouths,
and dwell in meditation with your minds."

(Attaining Buddhahood in This Body, Kobo Daishi)

However, if you know you cannot attain Buddhahood in this body and you wish to attain it in the Pure Land after death, follow this modified advice:

Put your hands in gassho,

say Namo Amida Bu with your mouth

and entrust to Amida Buddha with your mind.

This is similar with following the instructions of Amida in His Primal Vow:

“entrust yourself to me, say my Name and wish to be born in my Land”.
