TRANSLATION
All the learned scholars have given their opinion. The mind is by nature very restless, and one should not make friends with it. If we place full confidence in the mind, it may cheat us at any moment. Even Lord Śiva became agitated upon seeing the Mohini form of Lord Kṛṣṇa, and Saubhari Muni also fell down from the mature stage of yogic perfection.
PURPORT
The first business of one trying to advance in spiritual life is to control the mind and senses. As Śrī Kṛṣṇa says in  Bhagavad-gītā  (15.7):
mamaivāṁśo jīva-loke jīva-bhūtaḥ sanātanaḥ manaḥ ṣaṣṭhānīndriyāṇi prakṛti-sthāni karṣati
Although the living entities are part and parcel of the Supreme Lord and are therefore in a transcendental position, they are still suffering in this material world and struggling for existence due to the mind and the senses. To get out of this false struggle for existence and become happy in the material world, one has to control the mind and senses and be detached from material conditions. One should never neglect austerities and penances; one should always perform them. Lord Rṣabhadeva personally showed us how to do this. In the  Śrīmad-Bhāgavatam  (9.19.17) it is specifically stated:
mātrā svasrā duhitrā vā nāviviktāsano bhavet balavān indriya-grāmo vidvāṁsam api karṣati
