Answer
First of all, our business is not to curse anyone, and in any case, such curses would have no effect if we lack the required spiritual potency.
The real solution is the same one demonstrated by the great rishis.
We should sincerely chant the holy name and hear attentively. By doing so, we create a powerful spiritual influence within the atmosphere.
The rishis did not personally engage in political violence. Their strength lay in their spiritual power.
As more and more devotees become purified through chanting, their consciousness becomes increasingly powerful.
Our goal should be to become powerful rishis in the true spiritual sense—pure devotees.
Such purified consciousness has the power to influence the world.
Even worldly leaders are not fully independent. They are also controlled by the modes of material nature.
When devotees develop a powerful desire for the welfare of the world and chant purely, that spiritual force acts as a counterforce against destructive influences.
If pure devotees sincerely desire peace in the world, spiritual energies naturally begin to counter those forces that destroy peace.
Therefore, our primary responsibility is not merely external activism, but cultivating the desire that:
the world should function according to the Lord's will,
people should become free from sinful activities,
and everyone should receive the opportunity for spiritual advancement.
The material world is certainly a place of suffering because birth, death, old age, and disease cannot be avoided.
Still, it is also part of the Lord's arrangement.
Within that arrangement, peaceful societies are possible.
There can be prosperous civilizations where people live honestly, without starvation, poverty, theft, dishonesty, or unnecessary violence.
Such peace is possible when society follows the laws of karma and lives according to dharma.
When large numbers of people become sinful, Krishna descends in different incarnations to protect innocent devotees and restore religious principles.
Meanwhile, sincere devotees continue their spiritual practices, gradually giving up material attachment and increasing their attachment to Krishna until they return to Him.
The Lord allows every living entity the freedom to choose its own path.
The practical contribution devotees can make is to increase the spiritual force on the earth through sankirtana.
When the holy name is chanted, the Lord personally manifests through His transcendental name.
The all-pervading Lord responds according to our surrender, but through congregational chanting His presence becomes especially manifest in this world.
The more the holy name vibrates,
Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare, Hare Rama, Hare Rama, Rama Rama, Hare Hare,
the more peace, purity, and spiritual strength spread throughout society.
The holy name is the source of all positive spiritual energy.
Its transcendental vibration counteracts many negative forces present in the world.
Just consider a temple.
If congregational chanting were stopped, very quickly quarrel, hypocrisy, and material consciousness would dominate the atmosphere.
The peace and happiness experienced in devotional communities come from the transcendental effect of the holy name upon everyone's consciousness.
Unlike ordinary material sound, which is produced by vibrations in the air, the holy name is chinmaya-shabda—the Lord Himself manifesting through His transcendental name.
By hearing and chanting this transcendental sound, one's consciousness becomes purified and gradually rises beyond the three modes of material nature, even while living in this world.
