There is a context in Shrimad Bhagwat Katha Purana that Abhimanyu’s son Raja Parikshit was bitten by a snake named Takshak due to the curse of Shringi Rishi. Annoyed by this, Janamejaya, the son of Parikshit, organized a snake sacrifice to kill the snakes, due to which snakes started falling in the Yagya Kund, but Takshak, the leader of the snakes, could not come. When Janamejaya came to know that Takshaka was clinging to the throne of Indra, the king of the gods, for his protection, so the sacrifices were going in vain, then he chanted the mantra ‘Indraya Swaha-Takshakaya Swaha’. Due to this, Indra and Takshak snakes along with the throne were drawn to the Yagya Kund.
This story points towards the five sense organs of man and their negative desires like snakes. In fact, the human mind is the sixth sense, which is the king and is attached to the five sense organs, eyes, ears, nostrils, tongue and skin. Evil vision from the eyes, bad hearing from the ears, negative air intake from the nose, bad taste and bad words from the tongue and unwanted touch from the skin are no less than a poisonous snake. The positive feelings of a man are indicative of the deities, while the negative feelings and thoughts put him in the category of demons. When the feeling of negativity completely clings to the mind, then the person becomes a reservoir of habits of thoughts like lust, anger, greed.
Man is a slave of his habits. To get rid of it, one has to perform Yagya like Janamejaya, only then he can sacrifice the snakes of negative habits of birth after birth. The meaning of birth-birth should be taken from generation to generation, because it is a pole-truth that there is a hereditary effect on a human being. Man can achieve the best life only through good rituals in life.
