By taking the teachings to heart, Purity can be attained. The pure heart directed towards God and reflecting His image is indeed Heaven, Vaikuntha or Kailasa. Then you get security and peace. Perfect peace means the type of peace derived as a result of the absence of desire, anger, greed and hatred. Then peace becomes perfect, the highest and most stable type.
Genuine peace is won by control of senses.
Pure love can emanate only from a heart immersed in peace. Peace is another name for steadiness of the mind. Accumulation of riches and power cannot endow peace. Peace can come only from the fountain of peace within. By knowing that you are the Atma , which has no birth or death, no joy or grief, no up and no down.
