Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 44

Sanskrit:

योगचर्यामिमां योगी विचरन् मदपाश्रय: ।नान्तरायैर्विहन्येत नि:स्पृह: स्वसुखानुभू: ॥ ४४ ॥

ITRANS:

yoga-caryām imāṁ yogīvicaran mad-apāśrayaḥnāntarāyair vihanyetaniḥspṛhaḥ sva-sukhānubhūḥ

Translation:

The yogī who has taken shelter of Me remains free from hankering because he experiences the happiness of the soul within. Thus while executing this process of yoga, he is never defeated by obstacles.

Purport:

According to Śrīla Śrīdhara Svāmī, the Supreme Lord has briefly described to Uddhava the essential wisdom of all the Upaniṣads, with the conclusion that pure devotional service to the Lord is the real means of ultimate liberation. In this regard Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura emphasizes that although haṭha-yogīs and rāja-yogīs try to make progress along their prescribed paths, they confront obstacles and often fail to achieve their desired goals. However, one who surrenders to the Supreme Lord will certainly be victorious on his spiritual path back home, back to Godhead.
