Sundar Kand Verse 7
जेहिं गिरि चरन देइ हनुमंता। चलेउ सो गा पाताल तुरंता॥ जिमि अमोघ रघुपति कर बाना। एही भाँति चलेउ हनुमाना॥ ४॥
jehiṃ giri carana dei hanumaṃtā| caleu so gā pātāla turaṃtā|| jimi amogha raghupati kara bānā| ehī bhā~ti caleu hanumānā|| 4||
jehim giri carana dei hanumamta caleu so ga patala turamta jimi amogha raghupati kara bana ehi bha~ti caleu hanumana 4
The mountain upon which Shree Hanuman placed his feet instantly sank into the nether world under the force of his spring. Just as the unerring arrow of Shree Raghunath speeds to its mark, so Shree Hanuman surged forward through the sky.
जिस पर्वत पर हनुमान् जी ने पैर रखा, वह तुरन्त ही पाताल में धँस गया। जिस प्रकार श्री रघुनाथ जी का अमोघ बाण चलता है, उसी प्रकार हनुमान् जी चले।
This is verse 7 of 351 in Sundar Kand (सुन्दरकाण्ड), from the section “Mangalacharan & Departure” of Goswami Tulsidas’ Ramcharitmanas.
