Karmanyevaadhikaraste ma phaleshu kadachana
Ma karmaphalaheturbhurma te sangostvakarmani.
Thy business is with the action only, never with its fruits;
so let not the fruits of action be thy motive, nor be thou to inaction attached.
Bhagavad Gita: Chapter 2-47
Once you have set the spiritual goals for your self, be true to yourself.
Create a greater and ever greater measure of coordination between your thought, word and deed.
Say what you think and do what you say. Shed all hypocrisy. Remove all hypocrisy from your life. Hypocrisy is the sworn enemy of Peace of Mind.
On the material plane, witness those who are less fortunate than you and on the spiritual plane witness those who are more fortunate than you. This will induce material contentment and awaken spiritual content in you. That way lies progress and peace.
But if you do the other way round – witness those who are materially more well off and those who are spiritually inferior – it will develop disastrous effects of material discontent and spiritual pride.
Stick to a few tested friends. Do not multiply acquaintances. Do not become intimate with anyone. Respect your alone time in your Sadhana practice. This advice is because familiarity can breed contempt, disturb emotions and upsets peace of mind.
Talk only with purpose. Abstain from all unnecessary talk and gossip. Speak measured words. Even innocent, well meant words, are quite often misunderstood and they produce discord.
Never advise anyone on anything, unless you are asked to.
Mind your own business in your Sadhana.
