Sankaracarya's Vivekachudamani 420

संसिद्धस्य फलं त्वेतज्जीवन्मुक्तस्य योगिनः ।

बहिरन्तः सदानन्दरसास्वादनमात्मनि ॥

saṃsiddhasya phalaṃ tvetajjīvanmuktasya yoginaḥ |

bahirantaḥ sadānandarasāsvādanamātmani ||

(Sankaracarya's Vivekachudamani 420)

The perfected Yogi who is liberated-while-living, gets this as a result—in himself he enjoys the Bliss Eternal, both within and without.

A yogi or a pure devotee who is fully surrendered to the Lord is always protected. In Srimad Bhagavatam Chapter 6.3.27 Yamarāja warned his servants, "My dear servants, despite what you may have done previously to disturb the devotees, henceforward you should stop. The actions of devotees who have surrendered unto the lotus feet of the Lord and who constantly chant the holy name of the Lord are praised by the demigods and the residents of Siddhaloka. Those devotees are so respectable and exalted that Lord Viṣṇu personally protects them with the club in His hand. Therefore, regardless of what you have done this time, henceforward you should not approach such devotees; otherwise, you will be killed by the club of Lord Viṣṇu. This is my warning. Lord Viṣṇu has a club and cakra to punish non-devotees. Do not risk punishment by attempting to disturb the devotees. Not to speak of you, if even Lord Brahmā or I were to punish them, Lord Viṣṇu would punish us. Therefore do not disturb the devotees any further."
