The simple way to worship the Supreme Lord in this age of disturbance is to hear and chant about His great activities. The mental speculators, however, think that the activities of the Lord are imaginary; therefore they refrain from hearing of them and invent some word jugglery without any substance to divert the attention of the innocent masses of people. Instead of hearing of the activities of Lord Kṛṣṇa, such pseudo spiritual masters advertise themselves by inducing their followers to sing about them. In modern times the number of such pretenders has increased considerably, and it has become a problem for the pure devotees of the Lord to save the masses of people from the unholy propaganda of these pretenders and pseudo incarnations.
The Upaniṣads indirectly draw our attention to the primeval Lord, Śrī Kṛṣṇa, but the Bhagavad-gītā, which is the summary of all the Upaniṣads, directly points to Śrī Kṛṣṇa. Therefore one should hear about Kṛṣṇa as He is by hearing from the Bhagavad-gītā or Śrīmad-Bhāgavatam, and in this way one's mind will gradually be cleansed of all contaminated things. Śrīmad-Bhāgavatam (1.2.17) says, "By hearing of the activities of the Lord, the devotee draws the attention of the Lord. Thus the Lord, being situated in the heart of every living being, helps the devotee by giving him proper directions." The Bhagavad-gītā (10.10) confirms this: dadāmi buddhi-yogaṁ taṁ yena mām upayānti te.
The Lord's inner direction cleanses the devotee's heart of all contamination produced by the material modes of passion and ignorance. Nondevotees are under the sway of passion and ignorance. One who is in passion cannot become detached from material hankering, and one who is in ignorance cannot know what he is or what the Lord is. Thus when one is in passion or ignorance, there is no chance for self-realization, however much one may play the part of a religionist. For a devotee, the modes of passion and ignorance are removed by the grace of the Lord. In this way the devotee becomes situated in the quality of goodness, the sign of a perfect brāhmaṇa. Anyone can qualify as a brāhmaṇa if he follows the path of devotional service under the guidance of a bona fide spiritual master.
