So aṣṭāṅga-yoga, meditation, that is not possible. But if you are satisfied by doing some imitation, that is different thing. But if you want right perfection, then you have to execute all the different, I mean to say, stages of yoga practice, aṣṭāṅga-yoga. There are eight divisions: dhyāna, dhāraṇā, āsana, prāṇāyāma . . . so if it is not possible, then it is waste of time.
What is the ultimate goal of yoga process or meditation? To contact the Supreme, the Supersoul, the Supreme Lord. That is the aim and object of yoga process. Similarly, philosophical research, jñāna process, that is also, the aim is to understand Supreme Brahman, realize Brahman. So they are recognized process undoubtedly, but according to authoritative description, those processes are not practical in this age. Kalau tad dhari-kīrtanāt. Therefore one has to take to this process of hari-kīrtana.
Anyone can take, without any prequalification. You haven't got to study philosophy or Vedānta. This Vedānta philosophy was very much discussed between Prakāśānanda Sarasvatī . . . Prakāśānanda Sarasvatī asked first of all Caitanya Mahāprabhu that, "I understand that You were a very good scholar in Your previous life." Caitanya Mahāprabhu actually was a very great scholar. His name was Nimāi Paṇḍita.
And at the age of sixteen years old He defeated one great scholar from Kashmir, Keśava Kāśmīrī. So He was a great scholar. So Prakāśānanda Sarasvatī asked Him that, "I understand that You are a great scholar, Sanskrit scholar, and especially in logic You are a very good scholar. And You are now sannyāsī. You were born in a brāhmaṇa family. How is that You are chanting and dancing without reading Vedānta?"
This was the first question made by Prakāśānanda Sarasvatī. And He replied: "Yes. The thing is that when I was initiated by My spiritual master, he said that 'You are fool number one. You don't discuss Vedānta. Simply You will spoil Your time. Please take to this chanting Hare Kṛṣṇa, and You will be successful.' " That was His reply.
