kalo mahan vyatiyaya
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Hiranyakasipu thus passed a long time being very much proud of his opulences and transgressing the laws and regulations mentioned in the authoritative sastras. He was therefore subjected to a curse by the four Kumaras, who were great brahmanas.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
There have been many instances in which demons, after achieving material opulences, have become extremely proud, so much so that they have transgressed the laws and regulations given in the authoritative sastras. Hiranyakasipu acted in this way. As stated in Bhagavad-gita (16.23):
yah sastra-vidhim utsrjya
na sa siddhim avapnoti
na sukham na param gatim
“He who discards scriptural injunctions and acts according to his own whims attains neither perfection, nor happiness, nor the supreme destination.” The word sastra refers to that which controls our activities. We cannot violate or transgress the laws and regulative principles mentioned in the sastras. Bhagavad-gita repeatedly confirms this.
tasmac chastram pramanam te
karma kartum iharhasi
“One should understand what is duty and what is not duty by the regulations of the scriptures. Knowing such rules and regulations, one should act so that he may gradually be elevated.” (Bg. 16.24) One should act according to the direction of the sastra, but the material energy is so powerful that as soon as one becomes materially opulent, he begins to transgress the sastric laws. As soon as one transgresses the laws of sastra, he immediately enters upon the path of destruction.
