Here below Srila Prabhupada says Chant and be Happy
Lecture on SB 7.9.10 -- Montreal, July 9, 1968: avagamaṁ dharmyaṁ. There are many types of religious principles or religiousness, but here is the religion which you can directly perceive. Which you can directly perceive. Pratyakṣa avagamaṁ dharmyaṁ. And su-sukhaṁ. Su-sukhaṁ means very easy to perform, very easy. Anyone, even a child, can perform. Su-sukhaṁ kartum avyayam. Avyayam means imperishable. If you chant for a minute, it will never go in vain. Avyayam. It will never go in vain.
A great opportunity. So we should take this opportunity. Pratya Rāja-vidyā rāja-guhyam. This is called rāja-vidyā, the knowledge, the king of all knowledge. Rāja-guhyam, the king of all confidential things. Rāja-vidyā rāja-guhyaṁ pavitraṁ paramam idam, and very pure, and sublime. Pratyakṣa avagamaṁ dharmyaṁ, and it is directly perceived, su-sukham, and very easy to perform, avyayam, never to be destroyed. Whatever you do, that is your asset. If you do one percent, that is your asset. So actually it is so. So our request is that you take up this chanting and be happy.
