Dear Guest,
Questioning is one of the frist steps on the process to understanding. At least you acknowledge there is God. Here is my answer:
arjuna uvāca
sthāne hṛṣīkeśa tava prakīrtyā
jagat prahṛṣyaty anurajyate ca
rakṣāḿsi bhītāni diśo dravanti
sarve namasyanti ca siddha-sańghāḥ
Arjuna said: O master of the senses, the world becomes joyful upon hearing Your name, and thus everyone becomes attached to You. Although the perfected beings offer You their respectful homage, the demons are afraid, and they flee here and there. All this is rightly done.
kasmāc ca te na nameran mahātman
garīyase brahmaṇo 'py ādi-kartre
ananta deveśa jagan-nivāsa
tvam akṣaraḿ sad-asat tat paraḿ yat
O great one, greater even than Brahmā, You are the original creator. Why then should they not offer their respectful obeisances unto You? O limitless one, God of gods, refuge of the universe! You are the invincible source, the cause of all causes, transcendental to this material manifestation.
tvam ādi-devaḥ puruṣaḥ purāṇas
tvam asya viśvasya paraḿ nidhānam
vettāsi vedyaḿ ca paraḿ ca dhāma
tvayā tataḿ viśvam ananta-rūpa
You are the original Personality of Godhead, the oldest, the ultimate sanctuary of this manifested cosmic world. You are the knower of everything, and You are all that is knowable. You are the supreme refuge, above the material modes. O limitless form! This whole cosmic manifestation is pervaded by You!
vāyur yamo 'gnir varuṇaḥ śaśāńkaḥ
prajāpatis tvaḿ prapitāmahaś ca
namo namas te 'stu sahasra-kṛtvaḥ
punaś ca bhūyo 'pi namo namas te
You are air, and You are the supreme controller! You are fire, You are water, and You are the moon! You are Brahmā, the first living creature, and You are the great-grandfather. I therefore offer my respectful obeisances unto You a thousand times, and again and yet again!
namaḥ purastād atha pṛṣṭhatas te
namo 'stu te sarvata eva sarva
ananta-vīryāmita-vikramas tvaḿ
sarvaḿ samāpnoṣi tato 'si sarvaḥ
Obeisances to You from the front, from behind and from all sides! O unbounded power, You are the master of limitless might! You are all-pervading, and thus You are everything!
