pramādādatha vibhraśyed īśaṃ prati vicintyatām
prāgeva ceha dṛśyante bhūtānāṃ kāryasaṃbhavāḥ //

When Indra thus besought Cupid to fulfil his desires, the latter said—"Lord of the universe! Lord Śiva is unconquerable by my resources which are terrifying to the Munis and Dânavas and do you not know this? You know the glory of the mighty Śiva very well. Perhaps the blessings and wrath of the great are also great, there is always greatness in the great You have thought of your advantage in the enticement of Śiva This is not right, for, such schemes against Iśvara, launch one into utter ruin It had been witnessed many times before that The intentions of the beings become known and those who are overanxious to gain their ends, do not attain their ambition"—212 216
