I advise the abhyasis generally to sit in a natural, easy posture. Moreover, even those who assume a tight, straight pose are found to give way automatically to a suppliant, slightly forward-drooping posture as the state of blissful absorbancy sets in. As such, it may be considered to be more natural, even for the purpose of an ascent into higher states of consciousness
If we understand it (love) correctly, we find love is giving, and the more one gives, the more one loves, and we can therefore say with confidence that one gives totally when one loves totally. And this is what the master gives. He comes to us totally Himself and gives Himself totally to us in an endeavour, in an effort, to make us like Himself.
