In order to be recognized by Kṛṣṇa, the Supreme Personality of Godhead, one should chant the holy name of the Lord continuously, twenty-four hours a day ….. In His Śikṣāṣṭaka, Lord Caitanya Mahāprabhu wrote, paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam : all glories to the holy names of Lord Kṛṣṇa, which from the very beginning purify the heart and immediately liberate one. Bhava-mahā-dāvāgni-nirvāpanam.  If the real purpose of all yoga is to please Lord Kṛṣṇa, then this simple bhakti-yoga system recommended for this age is sufficient.
