Brahmastra (Nuclear weapon)!

Verses 1.7.19 to 21: Dvija-bandhu, brahmana only by birth but no qualification. Character and quality determines the caste, not by birth.

Those days, nuclear weapons were given to a person who could control his senses. That is because he would use it only for the right purpose. But when you give power to unqualified persons, he abuses the facility. Here we see that Ashwattama abused the facility he had of using a nuclear weapons. Because he was not a brahmana, he also did not have the power to withdraw that weapon. He simply wanted to use it, without thinking of the consequences, just because he had it.

Intoxication: If we are abusing the powers given to us, then we are getting intoxication. It is both gross and subtle.
We should pray to Krishna very deeply that please Krishna do not let me get intoxicated in any manner. Chanting sincerely will help in this process.
