Iti rāma-padenāsau paraṁ brahma ity abhidhīyate (CC Madhya 9.29). Rāma. Rāma means rāman. Rāma. The Supreme Personality of Godhead, Lord Rāma. If you associate with Him, Rāma or Kṛṣṇa or Viṣṇu, Nārāyaṇa . . . Nārāyaṇa parā avyaktāt. He is transcendental.
So some how or other, if you make association with Him, if you are elevated to that position, then you get ananta, unlimited happiness. That is required. Because we are part and parcel of the Supreme Lord, sac-cid-ānanda-vigraha (Bs. 5.1). The Lord is eternal, blissful and full of knowledge. Similarly, we are also part and parcel; we are also eternal, blissful and full of knowledge. But because we are part and parcel, very small particle, therefore sometimes our knowledge becomes disturbed. Just like little boy and elderly man. The elderly man hardly commits mistake, but little boy commits so many mistakes because he has got little knowledge.
So because we, the living entities . . . we have got knowledge, but because our knowledge is limited, therefore sometimes our knowledge is covered by māyā. But the knowledge of the Supreme is never covered by māyā. Just like this cloud. Cloud covers the sky. If an insignificant portion of the sky is covered by cloud, the cloud cannot cover the whole sky. You'll never hear that "A cloud is on London; therefore the cloud is all over the world." No. Similarly, the knowledge is covered of the small particle Brahman, not of the Supreme Brahman. There are many instances.
So some how or other, our knowledge is now covered in this material existence, so we have to get out of this ignorance. For that purpose we require tapasya, tapo divyam (SB 5.5.1). Tapasya means voluntarily accepting some inconveniences. Voluntarily . . . just like a man is very happy in his family life. He has good house, good wife, good children and good bank balance, enjoying life, but śāstra says: "Now you are fifty years old, you must get out." So he has to get out. He cannot say that "I am so happy in my family life. My wife is so nice. My children are so obedient. I have got nice money, income.
