In summer season warm is not very pleasing, but in the winter season the same warmth is pleasing. So warmth is pleasing or painful according to the seasonal changes. Therefore Kṛṣṇa advised Arjuna that, "Don't be subjected to the seasonal changes." āgamāpāyino 'nityā: "They come and go. Don't be very serious about that. Whenever there is some reverse condition of life, don't be disturbed, because they will come and go."
So our real business is Kṛṣṇa consciousness. So how this Kṛṣṇa consciousness can be developed by the easiest method? Tatra tatrāñjasāyuṣman bhavatā yad viniścitam. Now, this question is asked from a person who is self-realized, not from a shopkeeper. Tad vijñānārthaṁ sa gurum evābhigacchet (MU 1.2.12). Here is a guru, because he has learned sufficiently from Vyāsadeva and other sages, therefore they are asking from him, not from a . . . āyuṣman. They are blessing, "Be blessed with long span of life." Although he was young, still he's asking, they're asking, great, great learned brahmin and sages, "What you have decided to be the easiest process to achieve the highest goal of life?"
Puṁsām ekāntataḥ śreyas. Ekāntataḥ, absolute. Śreyas. Śreyas means benefit. There are two kinds of benefit: one is called preyas and one is called śreyas. Preyas means immediately very pleasing. Immediately. The senses, sense satisfaction, very pleasing immediately. But śreyas means ultimate goal. Ultimately. Just like a child, for him preyas means he wants to play, he doesn't want to go to school, and . . . but his śreyas is that he must go to school, must be educated, so that his future life may be secure. That is called śreyas.
