”The area for meditation should be evenly leveled, clean and pure. It should be free from stone pebbles, should not be susceptible to fire, should not be a dry desert, free from worldly irritating noise and should not be too close to a body of water. It should be pleasing to the mind and should not irritate the eyes. In such a place a cave should be created where wind would not disturb and in that place one should engage the mind on mediating on the Lord.”

PURPORT BY SRI KRSNA BALARAM SWAMIJI
We have discussed previously that the place where concentration on the Lord is performed should be very comfortable and pleasing in every way. The mind will always remain disturbed if the place of meditation is, in some way, uncomfortable. The place should not be uneven or with bumps, it should be level. It should not be crooked like a triangle in shape. It should be nice and clean. It should be a place situated in goodness such as a temple of worship or a holy place or near the bank of Ganges or Yamuna rivers. It should be a place free from flammable articles or hazards from fire. It should be free from the scorching heat of sun and should not include irritating noises of worldly loud music or a place of quarrel. It should not be very close to a body of water where dangerous reptiles or aquatics can create trouble or a place where many people come to bathe. It should not be filled with smoke that may irritate the eyes and should not be a fearsome jungle, which may create a disturbance from ferocious animals. In such a place a nice residence should be made in where a seat should be placed for chanting and meditating on the Supreme Lord.
[Svetasvatara Upanisad, 2.9, KBS0015]
