"su means"

SB Canto 7

Su means "good," and vrata means "vow."

SB 7.4.44, Purport:

To know about the Supreme Personality of Godhead and the characteristics of His pure devotee, one must inquire from authorities like Devarṣi Nārada. One cannot inquire about transcendental subject matters from a layman. As stated in Śrīmad-Bhāgavatam (3.25.25), satāṁ prasaṅgān mama vīrya-saṁvido bhavanti hṛt-karṇa-rasāyanāḥ kathāḥ: only by association with devotees can one authoritatively understand the position of the Lord and His devotees. A devotee like Nārada Muni is addressed as suvrata. Su means "good," and vrata means "vow." Thus the word suvrata refers to a person who has nothing to do with the material world, which is always bad. One cannot understand anything spiritual from a materialistic scholar puffed up with academic knowledge. As stated in Bhagavad-gītā (18.55), bhaktyā mām abhijānāti: one must try to understand Kṛṣṇa by devotional service and from a devotee. Therefore Yudhiṣṭhira Mahārāja was quite right in wanting to learn further about Prahlāda Mahārāja from Śrī Nārada Muni.

CC Madhya-lila

CC Madhya 1.198, Purport:

The word su means "good," and viṣaya means "sense objects." When the sense gratificatory activities are performed under sinful conditions, they are called ku-viṣaya, bad sense enjoyment. In either case, either ku-viṣaya or su-viṣaya, these are material activities. As such, they are compared to stool.

CC Madhya 24.94, Purport:

The word sukṛtinaḥ is very important in this verse. Su means "auspicious," and kṛtī means "meritorious" or "regulated." Unless one follows the regulative principles of religious life, human life is no different from animal life. Religious life means following the principles of varṇa and āśrama.

Questions and Answers -- Montreal, August 26, 1968:

Prabhupāda: Su-dustaya. Su-dus... Tyaja means give up, and du means difficult, difficult, and su means very difficult. In any word, if you apply, affix the word su, it becomes hundred times more magnified. Just like buddhi. Buddhi is intelligence, and if you affix subuddhi, that means very, very intelligent. Similarly dustyaja, "difficult to give up," and when you affix this alphabet su, it becomes "very, very, very difficult."

1969 Correspondence

Letter to Upendra -- Los Angeles 5 July, 1969:

In the material world the energy is called Bhadra, and in the spiritual world the same Maya is called Subhadra. The only distinction is su and without su. Su means auspicious. So in the spiritual world, the same Maya works auspiciously, and in the material world the same Maya works inauspiciously. This auspiciousness and inauspiciousness is our own choice.
