As soon as you get a material body, immediately according to the seasonal changes . . . just like in London city sometimes you are feeling cold, sometimes you are feeling very warm as the season changes. So the material nature will go on changing, and because your material body is susceptible to all the influence of such changes, you will feel pains and pleasure. No pleasure; always pain.
The same warmth is pleasure at some time, and the same warmth is pain at the same time. 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?"
