Once a grhastha follower of Gaura-kisora dasa Babaji asked for siddha-pranali (ekadasa-bhava initiation).
Babaji Maharaja replied, “The Hare Krishna maha-mantra is a siddha-mantra. Within this mantra are the siddha-rupa of the Supreme Lord Krishna and the siddha-rupas of all living entities.
If you chant the maha-mantra purely, the syllables of the maha-mantra will gradually reveal the spiritual form, qualities, and pastimes of Shri Krishna.
This chanting will also reveal your eternal spiritual form, service, and the eleven particulars of your spiritual identity.”
