According to our calculation is they are immortal. Just like according to calculation of the pataṅga, our life is immortal. You see? They will calculate: "Oh, these human beings are immortal." But none of them are immortal. So we call them immortal, the demigods. Amareśāḥ.
So amareśāḥ, they are the bhṛgv-ādaya-ṛṣis, great ṛṣis, or Indra, Candra and so many demigods. They are looking after the management of this universe. Bhṛgv-ādayaḥ. But they are also attacked, contaminated, by these qualities of ignorance and passion and goodness. Some of them are in goodness; some of them are in passion; some of them in ignorance. They are not free. The proportion may be . . . because their duration of life is greater, far, far greater than ours, the proportion may be different, but they are not free.
That is stated here. Nobody is free. Anye ca ye viśva-sṛjo 'mareśā bhṛgv-ādayo 'spṛṣṭa-rajas-tamaskāḥ (SB 6.3.15). Spṛṣṭa: they are also contaminated. Nobody . . . unless one is completely free from this contamination, nobody is allowed to enter in the spiritual kingdom. Śuddha-sattva. Śuddha-sattva means . . . even one is situated in that sattva-guṇa, he is not completely pure. Sometimes the other two qualities, ignorance and passion, may attack.
