Pure devotional service should be free from the desire for any material benefit or for sense gratification, as these desires are cultivated through fruitive activities and philosophical speculation. Generally, people are engaged in different activities to get some material profit, while most philosophers are engaged in proposing transcendental realization through volumes of word jugglery and speculation. Pure devotional service must always be free from such fruitive activities and philosophical speculations. One has to learn Kṛṣṇa consciousness, or pure devotional service, from the authorities by spontaneous loving service.
This devotional service is a sort of cultivation. It is not simply inaction for people who like to be inactive or devote their time to silent meditation. There are many different methods for people who want this, but cultivation of Kṛṣṇa consciousness is different. The particular word used by Śrīla Rūpa Gosvāmī in this connection is anuśīlana, or cultivation by following the predecessor teachers (ācāryas). As soon as we say "cultivation," we must refer to activity. Without activity, consciousness alone cannot help us.
