"Sacred place" refers to places of pilgrimage. In India the yogis, the transcendentalists or the devotees all leave home and reside in sacred places such as Prayag, Mathura, Vrndavana, Hrsikesa, and Hardwar and in solitude practice yoga where the sacred rivers like the Yamuna and the Ganges flow. But often this is not possible, especially for Westerners. The so-called yoga societies in big cities may be successful in earning material benefit, but they are not at all suitable for the actual practice of yoga. One who is not self-controlled and whose mind is not undisturbed cannot practice meditation. Therefore, in the Brhan-Naradiya Purana it is said that in the Kali-yuga (the present yuga or age) when people in general are short-lived, slow in spiritual realization and always disturbed by various anxieties, the best means of spiritual realization is chanting the holy name of the Lord.
