Shloka 5.1.188
समुद्रलङ्घनारम्भः — Commencement of the Ocean-Crossing
स तां बुद्ध्वार्थतत्त्वेन सिंहिकां मतिमान्कपिः।।।।व्यवर्धत महाकायः प्रावृषीव वलाहकः।
sa tāṃ buddhvārthatattvena siṃhikāṃ matimān kapiḥ |
vyavardhata mahākāyaḥ prāvṛṣīva valāhakaḥ ||
Understanding Siṃhikā’s true intent, the intelligent monkey expanded into a gigantic form, like a cloud swelling in the rainy season.
Recognising the true nature of Simhika the clutcher of shadows, the wise Hanuman grew to a huge size like a cloud in rainy season.
Dharma permits force when necessary to remove unjust obstruction; Hanuman’s expansion is a measured, mission-protecting response to predatory adharma.
After identifying Simhika, Hanuman deliberately increases his size to counter her and regain freedom of movement.
Tejas (spiritual/heroic energy) guided by buddhi: power is deployed intelligently, not impulsively.
