SB 10.8.41

atho yathāvan na vitarka-gocaraṁ
 ceto-manaḥ-karma-vacobhir añjasā
yad-āśrayaṁ yena yataḥ pratīyate
 sudurvibhāvyaṁ praṇatāsmi tat-padam
Word for word: 
atho — therefore she decided to surrender unto the Supreme Lord; yathā-vat — as perfectly as one can perceive; na — not; vitarka-gocaram — beyond all arguments, reason and sense perception; cetaḥ — by consciousness; manaḥ — by mind; karma — by activities; vacobhiḥ — or by words; añjasā — taking all of them together, we cannot understand them; yat-āśrayam — under whose control; yena — by whom; yataḥ — from whom; pratīyate — can be conceived only that from Him everything emanates; su-durvibhāvyam — beyond our sense perception or consciousness; praṇatā asmi — let me surrender; tat-padam — at His lotus feet.
Translation: 
Therefore let me surrender unto the Supreme Personality of Godhead and offer my obeisances unto Him, who is beyond the conception of human speculation, the mind, activities, words and arguments, who is the original cause of this cosmic manifestation, by whom the entire cosmos is maintained, and by whom we can conceive of its existence. Let me simply offer my obeisances, for He is beyond my contemplation, speculation and meditation. He is beyond all of my material activities.
Purport: 

One simply has to realize the greatness of the Supreme Personality of Godhead. One should not try to understand Him by any material means, subtle or gross. Mother Yaśodā, being a simple woman, could not find out the real cause of the vision; therefore, out of maternal affection, she simply offered obeisances unto the Supreme Lord to protect her child. She could do nothing but offer obeisances to the Lord. It is said, acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet (Mahābhārata, Bhīṣma parva 5.22). One should not try to understand the supreme cause by argument or reasoning. When we are beset by some problem for which we can find no reason, there is no alternative than to surrender to the Supreme Lord and offer Him our respectful obeisances. Then our position will be secure. This was the means adopted in this instance also by mother Yaśodā. Whatever happens, the original cause is the Supreme Personality of Godhead (sarva-kāraṇa-kāraṇam). When the immediate cause cannot be ascertained, let us simply offer our obeisances at the lotus feet of the Lord. Mother Yaśodā concluded that the wonderful things she saw within the mouth of her child were due to Him, although she could not clearly ascertain the cause. Therefore when a devotee cannot ascertain the cause of suffering, he concludes:

tat te ’nukampāṁ susamīkṣamāṇo
 bhuñjāna evātma-kṛtaṁ vipākam
hṛd-vāg-vapurbhir vidadhan namas te
 jīveta yo mukti-pade sa dāya-bhāk

(Bhāg. 10.14.8)

The devotee accepts that it is due to his own past misdeeds that the Supreme Personality of Godhead has caused him some small amount of suffering. Thus he offers obeisances to the Lord again and again. Such a devotee is called mukti-pade sa dāya-bhāk; that is, he is guaranteed his liberation from this material world. As stated in Bhagavad-gītā (2.14):

mātrā-sparśās tu kaunteya
 śītoṣṇa-sukha-duḥkha-dāḥ
āgamāpāyino nityās
 tāṁs titikṣasva bhārata

We should know that material suffering due to the material body will come and go. Therefore we must tolerate the suffering and proceed with discharging our duty as ordained by our spiritual master.
