When the Sadhak wants to harm someone, like an enemy, he must energize ash with the Mantra by chanting the Mantra 5022 times and then sprinkle the ash on the target person's clothing. This will make the enemy suffer from whatever disease you have wished for him. - Ashok Mehta
To cure the enemy from the disease, the practitioner has to energize the ash by chanting the Mantra 1042 times and give it to the enemy to lick. This will cure him of his diseases. The enemy has to directly lick the ash with his tongue.
