Gems from the Bhagavad Gita-

He 

WHOSE  HAPPINESS  IS  WITHIN,

WHOSE  REJOICING  IS  WITHIN  AND

WHOSE  LIGHT  IS  WITHIN,

attains mergence in Brahman.

On Prayer-6:

Prayer is not asking, but a call to self-purification and inward search, and he who prays with his heart, even if it be without words, is at peace with himself and with the whole world – Gandhiji 

On Prayer-5:

Our prayer is a heart search.  It is a reminder to ourselves that we are helpless without His support – Gandhiji

Gems from the Mother(Pondicherry)-2:

It is absurd to ask for help and yet to have no trust; on the contrary, with confidence everything becomes so easy.

Gems from Swami Vivekananda-67:

We may convert every house in the country into a charity asylum, we may fill the land with hospitals, but our misery will still continue to exist until our character changes.

Gems from Mata Amritanandamayi-11:

In this materialistic age, more concentration can be gained through kirtan than through meditation. Today, the atmosphere is filled with so many different kinds of sounds. Because of that, concentration will not come easily and meditation will be made more difficult than ever before. These obstacles can be overcome, however, if one performs kirtan. Not only that; the atmosphere itself will be purified by your kirtan – Mata Amritanandamayi

Gems from Sri Aurobindo-3:

Hate not the oppressor, for, if he is strong, thy hate increases his force of resistance; if he is weak, thy hate was needless – Sri Aurobindo

Gems from the Buddha-30:

No matter how hard the past, you can always begin asgain – Buddha

Gems from Sri Ramakrishna-13:

One cannot have the vision of God as long as one has these three – shame, hatred, and fear - Sri Ramakrishna

Gems from Sathguru Jaggi Vasudev-23

Your very body is Earth.  Let us walk gently and sensibly on this planet – Sadhguru Jaggi Vasudev
