Svādhyāya means study, study of these Vedic literature. Without any guidance, if you . . . just like so many ladies and gentlemen, they purchase books from the market. They have heard that Bhagavad-gītā is very nice book. So svādhyāya. Svādhyāya means studying the scriptures. Studying the Vedic literatures, that is called svādhyāya. Svādhyāya. And tapaḥ. Tapaḥ means penance. Somebody is fasting. Somebody is in the solitary place in the jungle. They are meditating. So many, there are process of penances and austerities. And tyāga, and renunciation. Just like sannyāsī, renounced order of life.
So Lord says: "All these processes—the yoga process, the sāṅkhya process, the ritualistic process, or studying the Vedas or undergoing severe type of penance and austerities—all these processes, combined together or individually, they are not suitable for achieving Me. They are not."
So practically every process is condemned herewith by the Supreme Lord, condemned in this sense, that they can approach to a certain degree, certain extent, towards the final goal. But that process will never be able to achieve to the final goal unless this devotional process is added there. Plus this must be, the devotion, this Kṛṣṇa consciousness, because ultimate end is Kṛṣṇa, the Supreme Lord. As we have several times discussed that verse from the Bhagavad-gītā, bahūnāṁ janmanām ante jñānavān māṁ prapadyante (BG 7.19): "After many, many births, those who are actually intellectual, they come to Me and surrender to God, that 'Here is . . .' Vāsudevaḥ sarvam iti: 'God is everything.' Then he surrenders."
So one has to come. Maybe you go by the yoga process, maybe you go by the philosophical process, maybe you go by the ritualistic process, maybe that you go by penances and by study. But unless you reach to this point of Kṛṣṇa consciousness, your attempt . . . not failure, but there are different degrees. So people are satisfied with that different degrees only. They . . . hardly they try to reach the final goal. But if anyone wants to reach the final goal, then he has to take this process of Kṛṣṇa consciousness, bhaktir mamorjitā. That process alone can take you to the Supreme Lord.
So those who are intelligent, they take this simple process. Now, especially in this age, even you cannot perform any other process. You cannot perform perfectly yoga, you cannot perform the religious rituals, neither you can study. The circumstances are so unfavorable that these processes are not possible in this age.
