Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 1

Sanskrit:

श्रीभगवानुवाचजितेन्द्रियस्य युक्तस्य जितश्वासस्य योगिन: ।मयि धारयतश्चेत उपतिष्ठन्ति सिद्धय: ॥ १ ॥

ITRANS:

śrī-bhagavān uvācajitendriyasya yuktasyajita-śvāsasya yoginaḥmayi dhārayataś cetaupatiṣṭhanti siddhayaḥ

Translation:

The Supreme Personality of Godhead said: My dear Uddhava, the mystic perfections of yoga are acquired by a yogī who has conquered his senses, steadied his mind, conquered the breathing process and fixed his mind on Me.

Purport:

There are eight primary mystic perfections, such as aṇimā-siddhi, and ten secondary perfections. In this Fifteenth Chapter Lord Kṛṣṇa will explain that such mystic perfections are actually impediments to the development of Kṛṣṇa consciousness, and that therefore one should not desire them.
