Prabhupāda: It is the duty of the guru to engage his disciple in Deity worship, in cleansing the temple, dressing the Deity, decorating the Deity, so many engagements. So everyone should be engaged. If one is not competent to dress the Deity—everyone is competent—he can simply wash the temple and cleanse it. That will also help. There is no difference, that one who is cleansing the floor of the temple and one who is engaged directly in the Deity worship... There is no difference. They are all the same. Don't think that "I am engaged in cleansing the floor of the temple, and he is engaged in decorating the temple. I should be envious." No. There is no question of. Any kind of duty you are engaged... Sva-karmaṇā tam abhyarcya (BG 18.46).
If you cannot do something which is hard for you, you do anything for Kṛṣṇa under the direction of spiritual master, you'll get perfection. It is not that "I have to do this. I have to do that." No. Kṛṣṇa's service is manyfold. If one is unable to take one kind of service, the spiritual master can give him another kind of service. But both the services are accepted by Kṛṣṇa.
