There are certainly many Vedic injunctions, ritualistic and sacrificial performances, regulative duties, meditative techniques and speculative processes to attain knowledge, but Kṛṣṇa's direct order—"Always think of Me and become My devotee"—should be taken as the final order of the Lord and should be followed. If one is simply convinced of this order and comes to His devotional service, giving up all other engagements, one will undoubtedly attain success. To confirm this statement, Śrīmad-Bhāgavatam (11.20.9) says that one should follow other paths to self-realization only as long as one is not convinced of the direct order of the Lord Śrī Kṛṣṇa. It is the conclusion of Śrīmad-Bhāgavatam and Bhagavad-gītā that the direct order of the Lord is to give up everything and engage in devotional service.
