Spiritual advancement

The key discipline you must cultivate is Ahimsa (Absence of Violence).
It does not merely mean not injuring a living being. You should not
cause hurt even by a word, a look or a gesture. Tolerance, fortitude,
equanimity - these help you to be steady in Ahimsa. They will remove
all chance of your causing pain to others. This is called Sahana

(Forbearance) or Kshama (Forgiveness). Assess the worth of whatever
others do to you or say about you, and cultivate fortitude and the
understanding to appreciate their behavior and pardon their faults.
This capacity is as invaluable as truth, righteousness, renunciation
and compassion. This is all that one need to possess for spiritual
advancement.

Ponder over all the things for which you have cried so far. You will
find that you have craved only for paltry things, for momentary
distinctions, for fleeting fame. Instead, you should cry only for God,
for your own cleansing and consummation. You should weep, for the six
cobras that have sheltered themselves in your mind, poisoning it with
their venom: Lust, anger, greed, attachment, pride and malice. Quieten
them as the snake charmer does with his swaying flute. The music that
can tame them is the Name of God. Thereafter, they become playthings;
you can handle them as you please. When these are laid low, you will
gain equanimity and you will remain unaffected by honour or dishonour,
profit or loss, joy or grief.
