Prabhupāda: Comfortable situation is also sense gratification. Any situation, we shall have to serve Kṛṣṇa. That is Kṛṣṇa consciousness. Not that, "If it is comfortable to me, I shall do it." That is sense gratification. That is sense gratification. That is not spiritual, that is material. "Comfortable or uncomfortable, it doesn't matter. If Kṛṣṇa wants it, I must do it." That is wanted. That is wanted. As soon as I discriminate, "This is comfortable, this is uncomfortable," that is material.
Devotee (3): Prabhupāda, how can we know what type of service Kṛṣṇa . . .
Prabhupāda: Therefore you have got spiritual master. Why he is there? Therefore you have to accept spiritual master who will give you direction. You cannot do it. If you manufacture your own way, then go to hell. Yasya deve parā bhaktir yathā deve tathā gurau, tasyaite kathitā hy arthāḥ (ŚU 6.23). Kṛṣṇa is there; guru is there. Why should you manufacture your own way? If you are sincere, Kṛṣṇa will dictate from within. Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam.
