Our senses are very imperfect. That we can understand. For example, we are daily seeing the sun globe, but our experience is just like a disc because my eyes cannot see things placed in long distance, neither can see which is very near. Just like the eyelid is just attached to the eye, but I cannot see. This is imperfect. Neither we can see very close, neither we can see very long distance point, neither we can see in darkness. There are so many conditions. If those conditions are fulfilled, then our senses can act. Therefore it is to be understood that our senses are imperfect.
Therefore Bhāgavata says ataḥ, therefore, śrī-kṛṣṇa-nāmādi, Śrī Kṛṣṇa, the Supreme Personality of Godhead, nāmādi... Nāma means His name, His holy name, ādi, that is the beginning. To understand Kṛṣṇa is to begin chanting His name, nāma. Nāmādi. Ādi means in the beginning. Therefore we recommend the students to chant Hare Kṛṣṇa. Ataḥ śrī-kṛṣṇa-nāmādi. Nāma means after you understand or realize nāma, then you'll understand His qualities, transcendental qualities. When, in the Vedic scripture, when it is said that the Absolute Truth is nirguṇa... Nirguṇa means, guṇa means quality, and nir means negative. And nir, nir, na arthe. Nir also used to ascertain. So nirguṇa can be used in two senses. The first sense is negative, "no guṇa, no quality," and the second is "it is difficult to ascertain."
