Devotee: Purport: "Samādhi means fixed mind. The Vedic dictionary, the Nirukti, says, 'When the mind is fixed for understanding the self, this is called samādhi.' Samādhi is never possible for persons interested in material sense enjoyment, nor for those who are bewildered by such . . ."
Prabhupāda: Samādhi . . . the yoga process is to achieve the stage of samādhi. That means the mind being fixed upon the Supreme. But if our mind is . . . mind . . . nature of mind is always agitated, and if we artificially give impetus to the mind to be more agitated, then where is the question of samādhi? There is no question of samādhi. They'll never be able to concentrate the mind. That is not possible.
So in this age no process will be successful. Simply this process, this chanting Hare Kṛṣṇa. Anyone, it doesn't matter, in whatever condition he is, as soon as he will hear Hare Kṛṣṇa, he'll immediately join. His mind will be attracted immediately. Simplest process: vibration. There is no question of time to practice some breathing exercise, some sitting posture, because these things are not possible in this age. Simply we invite you to come here and simply join this chanting Hare Kṛṣṇa, and very quickly you'll be spiritually advanced. This is a fact. Otherwise there is no second alternative.
Go on.
Devotee: "Samādhi is never possible for persons interested in material sense enjoyment, nor for those who are bewildered by such temporary things. They are more or less condemned by the process of material energy."
Verse 45: "The Vedas mainly deal with the subject of the three modes of material nature. Rise above these modes, O Arjuna."
Prabhupāda: Yes. Traiguṇya-viṣayā vedā nistraiguṇyo bhavārjuna (BG 2.45). The exact verse is like that. The whole material world is working under three modes of material nature: the modes of goodness, modes of passion and modes of ignorance. Those who are acting in the modes of goodness, they are being elevated to higher standard of life.
