In plain words
No one can grasp the principle of God
In the Mahābhārata, Droṇācārya laid out the padmavyūha. To break through the padmavyūha is possible only for heroes, not for others. At that time Arjuna was not at home. Abhimanyu went to Dharmaja and asked him to give him leave. Dharmaja told him first to go and bring his mother's leave. ‘Your wife is with child. You are young; besides, your father Arjuna and your uncle Kṛṣṇa are not here. So do not go,’ said Subhadrā.
Unafraid, upon Droṇa the pot-born and the Kuru heroes, like the king of beasts, I spring forward, the lofty ranks of shattering divine great weapons scattering: instead of saying, ‘Win and come back, son; good will be yours,’ is it right for you to hold me back like this so fiercely, ‘Don't go, don't go’?
‘If I do not go when my enemies are calling me, I will be the one who brought disgrace on my clan and my lineage; this does not befit kṣatriyas,’ said Abhimanyu. At those words her heart melted.
When he went to crush the pride of the asura named Tāraka, the heroic protection given to Gaurī's son; when he went to slay the warrior Śambarāsura, the splendid protection given to Bhārgavī's son; when he went to end his mother's bondage, the spotless protection given to Vinatā's son; when he went to the forest to keep his father's command, the blessed protection his mother gave Rāghava: that auspicious protection, protection of the mind, protection of the body, the Rāma-protection, divine among protections, may it be your companion and your shadow, and guard you!
